I can do it if you'd like.

Should I do it or not?

Should I?

Ah.

>> On her way to work one morning down the path along the lake, a tender-hearted woman saw a poor, half-frozen snake.

(crowd murmuring) "Take me in, oh tender woman, take me in, for heaven's sake, take me in, oh tender woman," sighed the broken snake.

She wrapped him up all cozy in a curvature of silk and then laid him by the fireside with some honey and some milk.

Now she stroked his pretty skin, and then she kissed him and held him tight.

But instead of saying, "Thank you," that snake gave her a vicious bite.

(cheers and applause) (handcuffs locking) (siren blaring) "I saved you, I saved you, I saved you," cried that woman.

"And you've bit me, heavens, why?

You know your bite is poisonous, and now I'm going to die."

And he said, "Well, I'm a snake, right?

And so you brought me into your home, and it's hard to believe that you didn't know what I was.

I'm a professional killer, right?

Just because you brought me in doesn't mean I wasn't going to ultimately revert back to my basic form."

>> "Oh, shut up, silly woman," said the reptile with a grin.

"You knew damn well I was a snake before you took me in ."

(cheers and applause) >> He tapped into something in a very profound way that, that began to redefine the debate in the political year of 2016, and, and continues to redefine the, the politics of the country today.

At its heart, a plan by three unlikely outsiders to transform the Republican Party, make Trump president, and introduce a harsh new approach to immigration-- zero tolerance.

Steve Bannon-- political gadfly, filmmaker, and polemicist-- was its leader.

>> We called this place the embassy for the simple reason that we thought we were in an embassy in a foreign capital, that this was owned and run by the permanent political class.

>> NARRATOR: Bannon pushed Breitbart into what was known as "smash-mouth coverage" of Washington power politics.

>> I said, "Let's attack the real enemy, and the real enemy's the Republican establishment.

What we're going to do is just go after the House leadership, we're going to go after the Mitch McConnells, we're going to go after the donors.

>> NARRATOR: Bannon and Breitbart figured they had a wedge issue that could help them take down the Republican establishment-- immigration.

I was wrong to take such a hard line on, on immigration."

And that is an, a, a position that I've evolved on.

Look, they lost on immigration.

They're going to have to do something on immigration.

Because, you know, our country is a different place than it was 50 years ago.

So we'll see what happens.

>> NARRATOR: In the face of all that... >> The politics swirling around the possibility of... >> NARRATOR: Steve Bannon and Breitbart found themselves in the political wilderness.

>> More Republicans are now changing their stance... >> NARRATOR: Bannon decided to fight back.

He invited two of his closest allies to the embassy for a war council.

>> Stephen Miller and Jeff Sessions and myself had a dinner in this very room.

>> Bannon ordered from Dean and DeLuca steaks, and they drank a lot, and they ate a lot, and they talked long into the evening.

>> And the three of them, these are sort of, at the time, especially, people on the fringe of what you would consider the sort of Republican Party.

>> I mean, Jeff Sessions, when he was in the Senate, was always on the outer fringes of the Republican Party, never even entirely taken seriously, even by the hardliners within the Republican Party.

>> Sessions' shop was the leaders, the intellectual backbone of the immigration fight.

It came from Jeff Sessions' office, it came from Senator Sessions himself, and Miller at his right hand.

>> NARRATOR: 27-year-old Stephen Miller was Sessions' communications director.

>> You had a vocal press secretary in his 20s for a back-bench senator from Alabama, as far from power as you could get in Washington at that time.

>> NARRATOR: The three outsiders shared a belief America was threatened by the flow of immigrants into the country.

They were determined to do something about it.

>> They were very ambitious and felt like, if they could get the, the message right, that this might all fall into place.

>> NARRATOR: That night in 2013 at the Breitbart embassy, they talked about how to politicize immigration.

>> The one and two issues will be immigration and trade.

And that will be focused on workers, right?

And we're going to remake the Republican Party.

>> NARRATOR: Miller would handle the details of their grand design, a policy behind the politics: Fortress America.

>> The world according to Miller would be a world of walls.

Miller is a restrictionist.

He wants to have restricted entry for legal immigration as well as illegal immigration.

>> NARRATOR: But in order to make it happen, they would first have to stop immigration reform and take down the G.O.P.

establishment.

>> If you were sitting there that night, the audaciousness of what they were plotting was, uh, was astonishing.

And you wouldn't have given them much chance of success.

>> The Senate passed sweeping immigration reform in an historic... >> The bill by the Gang of Eight passed today... >> NARRATOR: As the bipartisan bill passed the Senate and headed to the House, the insurgents had to act.

>> Miller knew how Washington worked and understands the way levers get pulled in Washington, and how to push an agenda through that was an anti-establishment-type agenda.

>> NARRATOR: Miller had an outlet-- Bannon's Breitbart.

It was a formidable alliance.

>> "Sessions: Immigration Bill Will 'Hammer' Americans."

"Sessions Comes Out Swinging Against Secretive House Immigration Push."

"Sessions: Breitbart Doing 'Great Work' Getting Truth Out About Immigration Bill."

I mean, there's a, that's an essential thing to do if you're going to get movement, especially on an issue like immigration, where all of the organized interest groups are on one side.

>> Well, immigration reform finally happened.

>> For the first time in years... >> NARRATOR: With immigration front and center, the insurgents planned a show of force in the upcoming midterm elections.

>> What they decided they need to do was to find an example of someone they could take down in the Republican establishment.

And when they looked around, the guy that they thought was most vulnerable was Eric Cantor, the House majority leader.

>> NARRATOR: Majority Leader Cantor-- one of the most powerful members of the Republican establishment-- was being challenged in his primary by an unknown college professor.

>> My name is Dave Brat, and I'm a lifelong Republican and conservative.

>> NARRATOR: Polls showed Brat more than 30 points behind Cantor.

But Bannon saw opportunity.

>> I, he definitely knew it was coming, that also happened to be my home district, but I could feel it.

I knew that, that a guy like Brat could...

They were, they were very weak.

>> I will fight to stop amnesty for illegal immigrants... >> NARRATOR: Following Bannon's lead, Brat would use immigration against Cantor.

>> Cantor, can you believe this guy, can you believe Ryan?

>> NARRATOR: Breitbart swung behind Brat-- hard.

>> Eric Cantor, he's all in for amnesty.

>> NARRATOR: They set the agenda for right-wing radio.

>> You're a coward, Eric Cantor, you only... >> Eric Cantor, who wants amnesty; Paul Ryan, who I called a phony... >> Anything that became talking points on conservative radio were coming from Stephen and put on Breitbart.

And you had a transformation, where conservative radio hosts weren't clicking on Drudge Report on what to say, they were clicking on Breitbart.

>> There's a story on Breitbart, "Republican National Committee Declares War on ..." >> What are Republicans getting out of Eric Cantor being House majority leader?

I'm not sure.

>> And with that, I want to pass the baton to Senator Jeff Sessions... >> NARRATOR: The insurgents rolled out their big guns for Brat: Sessions.

>> That's worthy of Patrick Henry.

>> NARRATOR: And Steve Miller's ally... >> If Eric Cantor is reelected, heaven forbid... >> Talk-radio celebrity Laura Ingraham.

>> There's a good chance we'll have amnesty by the end of the year.

>> Eric Cantor is definitely in trouble in his district.

>> If Dave Brat here can get a big turnout, he's going to, he's going to make a difference... >> NARRATOR: They'd thrown everything they could at Cantor.

>> Eric Cantor's district, let's send a real message... >> NARRATOR: And on election night, the Republican establishment was in for a shock.

>> History-making upset, House Majority Leader Eric Cantor lost... >> This is a seismic shift.

>> NARRATOR: Cantor was defeated.

>> That took all of the establishment figures... >> And we took him down.

We took down Cantor with Dave Brat.

We took the, first time in the history of the Republic that a sitting majority leader had ever been beaten.

>> It is a stunning upset.

>> All of them were broadsided by this victory of Dave Brat's.

>> (chuckles) I think, what is the phrase that Steve Bannon always uses?

"The hobbits revolted."

You know, the hobbits woke up in the Shire.

>> People want a new Republican Party with fresh faces... >> NARRATOR: Republicans got the message.

The bipartisan immigration bill was dead.

>> I knew that night when I heard.

I was talking to my Republican... they were basically, "There's no reason for us to talk anymore.

This is not going anywhere."

>> House Majority Leader Eric Cantor's defeat is the end of immigration reform.

>> Dave Brat proved this issue moves votes, in terms of Republicans getting off the then-popular immigration bills.

It was no question, it was a turning point on the immigration issue.

>> The G.O.P.

infighting is escalating.

>> Not only does Brat's victory confirm that... >> NARRATOR: Two of the insurgents' seemingly impossible goals had been accomplished-- Cantor was out, and so was the immigration bill.

>> Any hope of an immigration-reform bill is dead.

>> NARRATOR: Now they would concentrate on finding a candidate for the presidency of the United States.

>> ...legislative priority for decades... >> NARRATOR: Bannon had been looking for years.

>> We had Palin in '08 and hoped that she'd run in '12.

>> Well, I'm not a member of the permanent political establishment.

>> You know, she, it just didn't work out.

>> That is not our destiny.

>> I actually worked with Lou Dobbs and tried to get Lou Dobbs to run in '12, as a populist.

>> That on the previous policies, if they were... >> I actually tried to talk Sessions into doing it.

And Sessions goes, he turns to me and goes, "It's not me.

I'm not going to do it."

He says, "But our guy will come along.

We'll find our guy."

And that guy, a couple of years later, turned out to be Donald Trump.

>> The House majority leader has lost to his... >> NARRATOR: In Manhattan, Donald Trump had watched the Cantor defeat.

Now he believed immigration as an issue was a dragon-slayer.

>> "Trump said he thinks Cantor's amazing loss can be traced to his stance on immigration policy."

>> NARRATOR: While Bannon and Breitbart educated Trump from the outside, Trump adviser Sam Nunberg worked from the inside.

>> Nunberg had realized that this issue of immigration has real salience with Republican voters.

The problem they had was, they couldn't get Trump to stay on topic-- famously short attention span.

And so Sam Nunberg came up with this idea, essentially a mnemonic device to keep Trump focused on the issue of immigration.

>> So, I said, "Well, why don't we say you're going to build a wall, because it's bigger.

You're going to build a wall.

And you'll, like, and you'll get Mexico to pay for it."

>> NARRATOR: Trump took it on the road, testing out different versions of the line.

>> We have to build a fence.

And it's got to be a beauty.

Who can build better than Trump?

I build; it's what I do.

>> He said it in Iowa that day.

And the crowd went nuts.

You can watch it.

The crowd went nuts.

>> If I run, I will tell you, the king of building buildings, the king of building walls, nobody can build them like Trump-- that I can promise you.

I can promise you that.

>> He said to me, "You know what, I'm talking about immigration, I feel it.

Sam, this is a movement.

This is a movement.

They get it-- they get it."

>> NARRATOR: He had found his issue, and now Donald Trump had an announcement to make.

>> The key moment is coming down the escalator.

And I'm sitting there watching.

We have five people up at Trump Tower.

We have Boyle leading an entire team.

We got wall-to-wall coverage.

>> When Mexico sends its people, they're not sending their best.

They're not sending you...

They're not sending you.

They're sending people that have lots of problems, and they're bringing those problems with us.

>> When he starts doing the over-the-top stuff, and I go, I said, "You watch, they're, they're going to bite hard, and they're going to bite hard and blow this up."

>> They're bringing drugs, they're bringing crime, they're rapists, and some, I assume, are good people.

>> Oh, my God.

I said, this is...

I said, "He's just buried every... they're going to go nuts.

CNN is literally going to broadcast 24 hours a day."

>> Donald Trump's comment about Mexican immigrants has created controversy nationwide.

>> Donald Trump's comments have triggered outrage... >> Trump not backing down from his controversial, some say racist, language.

>> I was waiting for Trump to take it back and say, "Oh, no, no, I didn't mean that Mexico's sending rapists; they're sending Rhodes Scholars, they're so much better than we are."

And damned if he never took it back.

So I had to say, "Okay, I'm for, I'm for this guy."

>> Ann, which Republican candidate has the best chance of winning the general election?

>> Of the declared ones, right now, Donald Trump.

(audience laughing) (audience cheering) >> NARRATOR: Bannon had his candidate: one who understood the politics of immigration.

>> I said, "This is our guy.

He's a very imperfect instrument, but he's a armor-piercing shell."

("Sweet Home Alabama" playing) I tell the guys, "He's going to go through this thing like a scythe through grass."

>> NARRATOR: The insurgents would throw their weight behind the candidate.

Bannon would push the Trump message from Breitbart.

And they gave him something else-- an essential endorsement from a sitting United States senator.

>> I want to just introduce you to him for a second, Senator Jeff Sessions.

>> Certainly, if you're an unconventional outsider candidate like Donald Trump, you actually do want some people who are part of the system... >> Wow.

What a crowd this is!

>> ...to validate your legitimacy.

And that was Jeff Sessions' most important role in the success of President Trump.

>> At this time in Americans' history, we need to make America great again!

>> NARRATOR: Also stepping out for Trump, another one of the insurgents.

>> Ladies and gentlemen, please welcome the senior policy adviser for Mr. Trump, Mr. Steve Miller.

>> How's everybody doing tonight?

>> He was the one who would get up there before Trump came in to speak and sort of rile up the crowd.

>> Donald J. Trump is going to secure the border, and he's going to build that wall.

(cheers) >> He would have this magic effect on the crowd.

And the crowd is loving it.

And I was, like, "Who is that guy? "

And they said, "Oh, that's Stephen Miller, that's, that's, that's the one who brings the crazy."

>> Are you ready to vote for a policy that puts Americans first?

And are you ready, are you ready, Texas, to vote for Donald J. Trump?

(cheers) >> NARRATOR: Miller got close to Trump... >> We will build a great wall along the southern border... >> NARRATOR: ...jotting ideas... >> Who's going to pay for the wall?

>> Mexico!

>> NARRATOR: ...keeping track of the musings... >> Anyone who illegally crosses the border will be detained.

>> NARRATOR: ...stoking the anger... >> He's going to drive the cars over the illegals.

>> NARRATOR: ...writing the fragments that became the speeches.

>> Zero tolerance for criminal aliens.

Zero, zero.

>> The polls were brutal for Donald Trump.

Clinton leading in every single national poll... >> NARRATOR: But by mid-August, the campaign was in trouble.

>> ...show that Clinton now has a double-digit lead over Trump, 46... >> Nationally, he's down by large margins in swing states.

>> Trump is down in national polls... >> NARRATOR: Then Bannon got a call from the candidate.

>> Breaking news this morning, Donald Trump is changing his campaign's... >> ...installing firebrand conservative Breitbart News boss Steven Bannon as chief executive... >> He has a brand-new campaign C.E.O., which is a new... >> NARRATOR: Now all three insurgents were at the epicenter, with direct access to a candidate who would use their immigration message as a political weapon.

>> I remember riding on the campaign plane with Sessions, Stephen Miller, Steve Bannon.

And they suddenly had this vessel in Donald Trump, and they were giddy.

I mean, they were really excited, like, "This is our moment, this is our historical moment."

>> The decision desk has called Pennsylvania for Donald Trump.

>> NARRATOR: And on election night, it all paid off.

>> This means that Donald Trump will be the 45th president of the United States.

>> Trump's victory, after having run on this anti-immigrant message, had precisely the effect that Bannon and Sessions had hoped for three years earlier, when they first sat in the Breitbart embassy.

It elevated immigration to the forefront of the Republican Party.

>> NARRATOR: Fox News had also received the message.

Now they were all in with Trump on immigration.

>> You want to know what this election was about?

Look at America's open borders, they're a mess, and they're not secure.

>> A weak federal government has allowed immigration in America to become a national scandal.

>> He's going to move very quickly on the immigration priorities that helped get him elected.

>> Fox News saw that the Republican Party had been changed by Donald Trump.

Immigration was the issue, and so Laura Ingraham and Sean Hannity and others would hammer that night in, night out.

>> I, Donald John Trump, do solemnly swear... >> NARRATOR: Steve Bannon was put at the top of the food chain as Trump's chief strategist; Stephen Miller, senior adviser to the president; and Jeff Sessions was given one of the most powerful jobs in the Cabinet-- attorney general.

>> All of a sudden, they're three of the most powerful people in the country.

(cannons firing) >> NARRATOR: On the wall in his war room at the West Wing, Bannon created an immigration action plan.

>> I said, "All we have to do is flood the zone.

Every day we hit them with three things, bang, bang, bang.

These guys will never, will never be able to recover.

But we got to start with muzzle velocity."

>> NARRATOR: The muzzle velocity-- a series of harsh executive orders commanding the government to build a wall, to detain, to deport, to prosecute.

>> This was Miller's tactic.

You know, while you still have all that political wind at your back after winning an election, just, you know, "Hit them big, hit them hard."

>> ...opportunity for him to meet with his secretary of defense, James Mattis... >> NARRATOR: Immediately, Trump caused outrage, delivering part of what Bannon called their "shock and awe approach."

>> "Protection of the nation from foreign terrorists' entry into the United States."

It's big stuff.

>> NARRATOR: It was known as the "travel ban," blocking entry to people from seven predominantly Muslim countries.

>> A scene of outrage at JFK Airport in New York, where... >> Protests all across the country, reaction from around the world... >> Now protests, outrage, and backlash... >> And immediately, chaos ensues.

There are protesters at the airports, uh, people are getting detained left and right.

>> Seattle police actually dispersed some crowds with pepper spray.

>> NARRATOR: Watching the chaos on television, Republican Congressman Charlie Dent called White House staffer Ben Howard.

>> I said, "Ben, you know, was this thing run by the Department of Defense?"

And he said, "Well, no."

"How about State?"

"No, no."

"Homeland Security?"

"Well, eh, sort of."

"Justice?"

"Eh..." And I said, "Well," I said, "Well, so who did this?"

He said, "Miller."

And I said, "Well, who the hell's Miller?"

I didn't know who Stephen Miller was at that moment.

I said, "Who's Miller?"

And he said, he said, "I don't want to get into it."

>> NARRATOR: At the White House, they knew who Stephen Miller was.

And a faction there wanted to keep him as far away from the president as possible.

>> You had the, the Bannon/Miller/Sessions faction, and then you had the the Gary Cohns, Jared Kushner, Ivanka Trump, Reince Priebus, and others.

>> We had the two camps start to develop-- the more establishment camp, and more the kind of disrupters, populist, nationalist camp.

And then everything eventually became a knife fight shortly thereafter.

>> NARRATOR: After the travel-ban backlash, Bannon's stack of harsh executive orders was put on hold.

His opponents in the West Wing were gaining ground with the president.

>> Why he surrounded himself by people actively opposed to his agenda-- why he did that, who knows?

Who knows?

He has surrounded himself with people who disagree with him.

Why did he hire his kids?

Could be narcissism-- "They love me for me!"

Who knows?

>> You're supposed to really push hard the first 100 days.

What is going on?

What are they waiting for?

>> The things you elected Trump to do don't seem to be happening.

>> NARRATOR: Bannon and Miller wanted to make sure a tough stance on immigration stayed on the agenda.

They would look up Pennsylvania Avenue to the Department of Justice, where Jeff Sessions was the boss.

>> Jeff Sessions is the nerve center of the Trump administration's anti-immigration agenda.

And Sessions wastes no time once he takes over at, at D.O.J., pretty systematically retooling the asylum system.

>> He's working on sanctuary cities.

He's trying to figure out a way to starve cities of funding.

And he's also working on what are basically the beginnings of the zero-tolerance policy.

>> NARRATOR: The insurgents placed dozens of allies throughout the government, many of them Sessions' former Senate staffers.

>> Jeff Sessions and the people he hired to work with him inside the Justice Department knew how to work that system.

They worked it early and often, and they used their power over immigration in ways we have not seen for a generation or more.

>> NARRATOR: They began checking off the boxes.

>> What Sessions is doing simultaneously is he is starting to pull all of the relevant levers to make sure that there are no impediments to mass deportation.

>> NARRATOR: But Jeff Sessions had a big problem.

>> This is an NBC News special report-- here's Lester Holt.

>> Good afternoon from New York.

We're coming on the air to bring you a news conference from... >> NARRATOR: The Russia investigation-- run by his own Justice Department-- was encircling the Trump White House and the president himself.

>> I have now decided to recuse myself from any existing or future investigations of any matter relating in any way to the campaigns for president of the United States.

Thank you all, take care.

>> We're watching TV on Air Force One.

And the president was very upset, because he felt like he was being abandoned.

And Trump is very angry, very frustrated, and Jeff Sessions and Donald Trump's relationship was never the same after that.

>> NARRATOR: It wasn't long before Trump confronted Sessions at the White House.

>> President Trump just berates Jeff Sessions.

Sessions is humiliated.

I mean, he's told people it was one of the low points of his professional career.

I mean, he's just completely dressed down.

>> NARRATOR: The grand design was in peril.

Sessions was preparing to resign.

Steve Bannon reacted.

>> I said, "You were there from the beginning."

I said, "You rode shotgun with me the entire time."

He goes, "Yep."

I said, "Is there any doubt in your mind that this was divine providence that put us here?

Right?

That this just didn't happen, that this, something's, something's worked here, because he's a very imperfect instrument, but we're here."

I said, "And you're never going to quit?"

He says, "I will never quit."

I go, "No matter how bad it gets?"

He goes, "I'll never quit."

>> NARRATOR: Sessions returned to the Justice Department to redouble his efforts on immigration.

>> It was the only place, pretty much, that anything was being done on Trump's promises.

So it was really fun to watch Trump humiliating Sessions every day on Twitter-- the one guy keeping your promises.

>> Trump has continued to rage against Sessions for his decision... >> President Trump today lashing out on Twitter once again... >> NARRATOR: At the D.O.J., Sessions was quietly laying the groundwork for a big move.

He wanted to roll back an Obama-era policy known as DACA-- protections for undocumented immigrants who had come to America as children.

>> DACA is a recognition and a realization that when somebody comes here as a child, they're brought here not of their own choice.

And we should recognize and acknowledge that and be compassionate toward those people.

>> NARRATOR: They were called "Dreamers."

But to Sessions and his allies, DACA was an amnesty that sent the wrong message.

>> One amnesty begets another amnesty, it begets more and more... You are creating a magnet for more and more illegal aliens to pour in, as every country that's ever tried an amnesty has discovered, and never done it again.

>> NARRATOR: Miller and Bannon needed the president to agree to end DACA.

But at his first press conference, they realized they had a problem.

>> Thank you very much.

>> The DACA program for immigration.

What is your plan?

Do you plan to continue that program or to end it?

>> We're going to show great heart.

DACA is a very, very difficult subject for me, I will tell you.

To me, it's one of the most difficult subjects I have, because you have these incredible kids.

You know, I love these kids, I love kids, I have kids and grandkids.

>> It became clear that he was really waffling on DACA.

And Bannon was getting really worried that this was actually becoming a problem, that Trump was not moving quickly to end it.

And he was actually seeming to be reluctant to do it at all.

>> NARRATOR: Bannon swung into action.

He reached out to a rising star from the hard right-- Kansas Secretary of State Kris Kobach.

>> Steve Bannon and Stephen Miller wanted to see movement on the DACA issue, wanted to see it rescinded.

>> Bannon says to him, "You, you got to have a way that we can, that we can kind of force this issue on DACA."

>> NARRATOR: The idea was to box Trump in.

Kobach would use ten conservative state attorneys general.

>> What Kobach and the attorney generals wanted to do was to get this up at the, at the right level.

And I think that's why the Texas A.G. took the lead, wrote a very powerful letter.

>> NARRATOR: The letter was a threat-- legal action against the Trump administration if they didn't stop DACA.

>> And so, I think that was an important piece of the puzzle, or an important shift in the landscape that helped, uh, move the administration.

>> All right, well, a major deadline for the Trump Justice Department looming early next month... >> That is when Texas and nine other states plan to sue the administration... >> NARRATOR: The letter worked.

Trump relented.

Sessions delivered the news.

>> Good morning.

I'm here today to announce that the program known as DACA that was effectuated under the Obama administration is being rescinded.

>> Jeff Sessions makes it pretty clear they will, in fact, be moving to possibly deport, um, thousands of people who were brought to this country as young children and who know no other home but America.

>> Thank you very much.

>> It's a pretty devastating blow to about 800,000 Dreamers... >> Protests erupting nationwide after the Trump... >> Major change in immigration policy announced today... >> And immediately, it's like a bomb goes off in Washington.

>> Immigrants are welcome here!

>> What the president called a case of heart now sparking emotional protests all over the country.

>> Can't go back home.

They can't send me go, back home, because this is my home.

>> As the community prayed over them, some broke down in tears.

They were all DACA recipients, now filled... >> Protesters storming major cities all across the country... >> Outrage after the Trump... >> ...decision impacting nearly 800,000 people... >> NARRATOR: As the negative coverage hammered the president, he made a political calculation.

He backed off.

>> "Does anybody really want to throw out good, educated and accomplished young people who have jobs, some serving in the military?

Really!"

(tweets) >> NARRATOR: To the insurgents, it seemed like they had lost the president.

>> Yet another bombshell.

>> NARRATOR: Their enemies were on the rise.

>> Mr. Trump's controversial chief strategist forced out... >> NARRATOR: After seven months, Steve Bannon was out.

>> How does Trump think he can get rid of Bannon?

Wasn't Bannon the guy that got Trump elected?

>> Over time, more and more Bushies arrived.

So more and more people who were from, from the swamp, who had long resumés, and were plugged into positions of, of importance and significance.

In part and parcel, it's, it's the reason for why I left the White House.

It may be the reason for why Steve left the White House when he did.

>> President Trump holding a critical meeting today with lawmakers.

>> Meeting over at the White House today... >> NARRATOR: With the insurgents weakened, Trump improvised.

They watched what they considered a mind-boggling event.

Congressional leaders-- including Democrats-- were invited to make a deal that could protect the Dreamers.

>> Here we are in the Cabinet Room, and I come in and notice, to my surprise, that my name plate is right next to the president of the United States, to his right.

Uh, I was not a close friend of this president.

>> NARRATOR: The president shocked the entire room when he allowed the cameras to stay for the meeting.

>> So now we have the press giving live coverage for this meeting.

>> I think we're going to come up with an answer.

I hope we're going to come up with an answer for DACA, and then we go further than that later on down the road.

Dick, perhaps you'd like to say a few words?

>> There is a sense of urgency that's felt by many of us when it comes to this issue.

1,000 a day will lose DACA protection.

900 of them are members of the U.S. military.

20,000 of them are school teachers.

Lives are hanging in the balance of our getting the job done.

>> I agree with that, Dick.

I very much agree with that.

>> And the president is referring to me as Dick all the time.

And I'm thinking, you know, "I, I guess I'm his friend at this point."

>> NARRATOR: On television, the president said he wanted to make a deal, have an agreement to save DACA.

>> When this group comes back, hopefully with an agreement-- this group and others, from the Senate, from the House-- comes back with an agreement, I'm signing it.

I mean, I will be signing it.

>> Senator Feinstein almost can't believe it.

Every Democrat sitting on the edge of their seat in that room, wondering, "Is the president about to break from his own party and cut a deal?"

>> I'd like to ask the question: what about a clean DACA bill now, with a commitment that we go into a comprehensive immigration-reform procedure?

>> Uh, I have no problem...

I think that's basically what Dick is saying.

We're going to come up with DACA, we're going to do DACA, and then we can start immediately on the phase two, which would be comprehensive.

>> Would you be agreeable to that?

>> Yeah, I would like, I would like to... >> He starts to actually get way beyond where, certainly, Stephen Miller, but a lot of his advisers are on the substance of what the deal would look like.

>> I'll take the heat, I don't care.

I don't care.

I'll take all the heat you want to give me, and I'll take the heat off both the Democrats and the Republicans.

My whole life has been heat.

I like heat, in a certain way.

>> It was, uh, it was disconcerting.

And I did have my head in my hands.

But I've had that a lot in listening to the president.

He is the kind of guy who, at least rhetorically, is, is going to be prone to just giving away the store, which is why even McCarthy, who's kind of a squish on all of these things, immediately piped up.

>> Mr. President, you need to be clear, though.

I think-- I think what Senator Feinstein is asking here, when we talk about just DACA, we don't want to be back here two years later.

You have to have security, as the secretary would tell you.

>> But I think that's what she's saying.

>> No, no, I think she's saying something different.

>> NARRATOR: To immigration hardliners, it was a reminder that the president could not be trusted.

>> It seems, I think, perfectly apparent to me, and anyone else who observes this president, he, he's impulsive, um, he says things off the top of his head.

He, um, bears the impression of, like a couch, bears the impression of the last person who sat on him.

Um, it's just, whoever gave him the last piece of advice, he goes out and says it.

>> I think I really agree with Dick, I think it'll happen.

>> Thank you all.

>> I hope we gave you enough material.

>> In an unusual move, cameras were rolling for nearly an hour on Tuesday... >> The president actually seemed open to comprehensive immigration reform.

>> NARRATOR: Just two days later, senators Dick Durbin and Lindsey Graham were ready to deliver the deal Trump asked for.

>> It included a future for DACA and Dreamers, it also included money for his wall.

I mean, it really was what he had asked for.

>> NARRATOR: Durbin let the White House know.

>> Within minutes, the president calls back.

"What can I do for you, Senator?"

"Well, Senator Graham and I have a bill."

He said, "Good."

>> NARRATOR: The president said he wanted to meet with the two senators that day.

>> I found that incredible.

I couldn't believe I could ever get in to see a president in short order like that.

>> NARRATOR: Miller had to move quickly.

>> One of Miller's talents was spinning the president up.

He was constantly handing him, you know, statistics and numbers and papers and links to Breitbart, links to Fox News clips.

>> NARRATOR: Miller's allies in the right-wing media sounded the alarm.

>> ...does not include a wall, a real wall... >> You know, they're all giggling that he's getting rolled.

>> NARRATOR: Talk radio turned up the volume.

>> This is the only thing that Donald Trump can do to possibly derail himself.

>> This is the end of the road for the Republican Party.

>> All of the right-wing media figures who championed Trump are losing their minds, because all of a sudden, everything Trump said during the campaign seems like it's up for debate, that he's willing to trade, trade all of his campaign promises away as bartering chips.

>> He shouldn't talk about immigration unless Stephen Miller is there to follow up... >> NARRATOR: Senators Durbin and Graham arrived at the White House with their deal in hand.

>> While they're waiting in the West Wing lobby, all of a sudden the doors open, and other people start coming in.

Tom Cotton, very, very conservative.

He has said publicly that, you know, "The DREAM Act is a nonstarter."

David Perdue, same thing, he walks through the door.

Then there's Bob Goodlatte, who's the Republican chairman of the House Judiciary Committee.

And then Stephen Miller walks in, and before they know it, they're all in the Oval Office, uh, all together.

>> It's really Miller who makes sure that the room is filled with immigration hardliners.

>> They're there to represent a position that they feel strongly about, which is, frankly, much closer to President Trump's position.

>> Well, things went south in a hurry.

Almost from his first word, you could tell that the president I spoke to two hours before, and the one two days before, who had invited us to come by, uh, had changed dramatically.

And now he was opposed to every part of it.

And that's when a lot of the profanity started flying.

>> And the president was already in an unhappy mood, because he kept reviewing all this migrant data from Miller.

And he just erupts.

He erupts.

It's gone from a chummy chat with the senators on camera, it's gone from cordial rapport with Senator Feinstein, to vulgarity in front of Senator Durbin and others.

>> NARRATOR: The vulgarity stunned the room.

>> He essentially says, "Why do we want all these people from shithole countries?"

At which point, everyone kind of stops.

>> He doesn't want people from Haiti or from Africa, countries that he refers to as "shithole countries."

He says he wants people from Norway.

And it's, it's impossible to ignore that the people he's talking about as, as undesirable are people of color and black people.

>> People will not come in to our country... >> And it's jaw-dropping, as he went through this long litany of grievances he had against immigrants in this country, particularly those from what he referred to as "shithole countries."

>> And all the while, Stephen Miller, once again, standing at the perimeter of the room, listening to that comment, and he knows that it's mission accomplished-- he's done what he, he wanted to do.

>> We are going to stop... >> NARRATOR: The immigration hardliners had won.

There would be no DACA deal.

The fate of the Dreamers would be in the hands of the courts.

♪ ♪ >> A week ago, Central Americans crossed from Guatemala into Mexico... >> 11,000 Central American immigrants... >> NARRATOR: Now, in the spring of 2018, from the Justice Department, Sessions and Miller would raise the ante.

It was time to crack down on the border.

>> They wanted to send a deterrent message through a very dramatic way in the hope that they would scare these people off and have them stay in Central America.

>> NARRATOR: Sessions released this tough directive using the words "zero tolerance."

>> So, Jeff Sessions is using the authority that was retained in the attorney general's office.

And he recognizes he's got a lot of levers that he can pull, he's got a lot of tools that he can use.

>> NARRATOR: Everyone who crosses the border would be prosecuted, even families with children.

>> If you smuggle illegal aliens across our border, then we will prosecute you.

If you are smuggling a child, then we will prosecute you.

And that child may be separated from you, as required by law.

>> NARRATOR: It became known as family separation.

(people talking on radio) Like the travel ban and DACA, family separation quickly turned into a crisis as the images were released.

>> Young children are pulled from the arms of their mothers.

It ushers in a part of America and a history of America that people are going to look at for years to come as the defining moments of the Trump presidency.

>> Children were separated from the adults with whom they arrived, and there wasn't meticulous association of those children with those adults.

(child crying) (children crying) (in Spanish): (in Spanish): >> Here's the thing that I think broke America's heart.

They didn't even know what they were doing, they weren't even keeping tabs on where these children and who their parents are and where their parents were at.

That's what they did.

>> All it's doing is showcasing unbelievable cruelty... >> The trauma of separating a child who doesn't know what's going on... >> NARRATOR: But Stephen Miller insisted it was all part of the grand design.

>> When I talked to Miller, he said that he believes anytime the country is focused on immigration, the president is winning.

So, when you're at the border getting footage of crying children being ripped from the arms of their mothers, that would seem to most people like bad, a bad development for the president.

To Stephen Miller, he thinks that this is just drawing the attention once again to the issue that we care about most, and, uh, and, he sees that as a win.

>> Where are the children?!

>> Anger over the Trump administration's policy of separating immigrant children from their families at the border... >> Some Democratic lawmakers are voicing their anger over the family separations.

>> The growing outrage over families being separated at... >> NARRATOR: The controversy quickly consumed Washington.

>> Hey there, everyone.

We're heading towards the Department of Justice.

>> The White House faces a growing backlash of anger... >> NARRATOR: For weeks, the president and the White House were under assault.

>> ...is struggling to explain and defend a practice... >> NARRATOR: Miller wanted to stay the course.

The president's own family were strongly on the other side.

>> Every day, yesterday, 70 kids, today, 70 kids... >> NARRATOR: Once again, Trump capitulated.

>> I'm signing an executive order I consider to be a very important executive order.

It's about keeping families together.

Ivanka feels very strongly.

My wife feels very strongly about it.

I feel very strongly about it.

I think anybody with a heart would feel very strongly about it.

We don't like to see families separated.

This takes care of the problem.

Thank you very much... >> I'm very disappointed in President Donald Trump... >> I think he's not getting the best advice on this, it's very disturbing.

>> NARRATOR: The insurgents had again lost control of what Bannon had called "the imperfect instrument."

>> Trump signs an executive order, and for the ten minutes it's going to survive... >> ...U.S. attorney general is stepping down, apparently at the request of President Trump.

>> NARRATOR: A few months later, Jeff Sessions was finally out.

>> Jeff Sessions, the attorney general of the United States, has submitted his letter of resignation... >> NARRATOR: Stephen Miller would be the only one of the original insurgents still on the inside.

>> Sessions didn't survive, and Bannon didn't survive, but Miller, who's the ultimate survivor, has managed to outlast pretty much everyone.

>> The ramifications are many.

>> Miller is a talented bureaucratic infighter.

Miller understood that, in order to survive and have influence with Donald Trump, you need to consistently display a fanatical degree of loyalty.

And Miller has always been willing to do that, publicly and privately.

>> A record number of migrant families have arrived at the southern border in recent months.

>> 144,000, that is the highest... >> NARRATOR: The president had signaled he was scaling back zero tolerance.

But there was an unintended consequence.

The number of migrants increased.

>> ...of migrant families surged after the Trump administration ended... >> The ending of the policy has a pretty pronounced effect on the numbers of people showing up.

The word gets back to Central America that "zero tolerance is not really zero tolerance anymore, that if you come with a child, in fact, you will not be separated from that child."

>> Right now, another... >> NARRATOR: On Fox, they called the caravans an invasion.

>> It's not a caravan, it's an invasion.

We have every right to be able to protect our borders.

>> And at this hour tonight... >> You know, what happens with the president and the caravans is he sees footage of them on Fox News and starts to fulminate against them, and it becomes to him this image of a border being overrun.

>> ...than 103,000 people were apprehended at the southern border last month... >> The president grows angrier and angrier by the week as he continues to hear new numbers, new data, about what's happening at the border.

He can fly into fits of rage.

Miller doesn't discourage this at all.

>> NARRATOR: For Miller, the crisis was an opportunity.

It was election season-- the 2018 midterms-- and Trump was in campaign mode.

>> So, the president's going all out for the next few days, hosting ten more rallies across the nation focusing on illegal immigration.

>> NARRATOR: Miller knew what would fire up the crowds.

>> We want our country to be a sanctuary for law-abiding Americans, not criminal aliens.

We're not playing games.

Because you look at what's marching up, that's an invasion.

>> The president uses that to drum up his election push for the midterms, and calls that election "the election of the caravan."

>> (chanting): Build the wall!

Build the wall!

>> NARRATOR: It was also the beginning of Trump's own re-election campaign.

>> The, the closer we get to 2020, the more this president and his advisers are saying, "Immigration is our fire.

That's the fire we put in our torch to try to win in 2020."

>> NARRATOR: Determined not to lose his base, Trump was firmly back on the side of the insurgents.

Now Miller would call the shots.

>> Stephen Miller is the point person at the president's side on the immigration issue.

He is a, a driving force in... And he has an awful lot of knowledge that he brings to bear at the president's right hand.

>> NARRATOR: Miller pushed controversial executive actions... >> ...announcing a new regulation that will allow migrant families... >> NARRATOR: ...cutting back on refugees... >> ...Trump administration changing the rules for migrants hoping to claim asylum in the United States.

(handcuffs locking) >> NARRATOR: ...building the wall... >> Trump to divert billions from the Pentagon, from the military, to build his border wall.

>> Targets hundreds of thousands of legal immigrants... >> NARRATOR: ..slashing legal immigration... >> ...Trump administration issuing a regulation that would deny green cards for legal immigrants... >> Immigrants are not welcome... >> NARRATOR: ...initiating raids across the country... >> ...thousands of people nationwide are bracing now for ICE raids President Trump's ordered to begin... >> Sweeps are expect to target about... >> NARRATOR: ...and igniting a firestorm.

>> ...kids might be left parentless in the process makes it all the more disturbing.

>> Officials called it the biggest worksite immigration enforcement operation... >> ...could close down our southern border... >> NARRATOR: It had been six years since that dinner at the Breitbart embassy.

Zero tolerance had won the day.

>> From the dinner we had, we'd brought border security up to the forefront.

Right now, we actually are engaged as a nation, and I think in 2020, it's even going to be more of a centerpiece in the national debate, as it should be.

>> NARRATOR: For Sessions, Bannon, Miller, it was all part of the grand design.

>> We are now debating all the topics on Donald Trump's turf, okay?

That, in, in January 2013, that looked like a pipe dream.

Today, that's the reality.
