Preparing for this kind of a case was necessary to speak to them, to listen to them, to earn their trust.

They have to believe in you.

If they don't want you to be the person to do it, then you shouldn't be doing it.

- [Luis] There was pushback fro the immigrants rights community.

They thought someone who was conservative couldn't tell our stories correctly or that there was a ulterior motive.

I don't know, I thought it was going to be helpful and, you know, I think, you know, the name of the game is to win and we knew the composition of the court.

We knew that there was mor conservative justices than not, and I think sometimes what's just as important as the message is the messenger.

- Ronald Reagan once said, “You can go to Japan” “but you can never become Japanese.” “Or you can go to Norway and never become Norwegian,” “but you can come to America and become an American."

We've all come to this country in various different ways and various, from various different places.

but I'm reminded of what brought about some of the most serious change in America, it's the direct action by people, not Congress, by people.

I do feel inspired that even if the decision goes the other way, that we're in a moment where we're shifting America to the promise that it's supposed to be.

Yo no podía creerlo cuando me dijo mamá, voy a ir a la Corte Suprema para lo de DACA.

Sí, dijo así de que a ti que te encanta mucho orar.

¡Ponte orar desde ahorita!

- Tomorrow, Supreme Court will hear arguments at 10:00 AM.

[light palpitating music] I'm very nervous.

[crowd chanting] - [Crowd] One, We are the people Two, a little bit louder, Three, we want justice for our people.

- There's a myth in this country that you only win in the Supreme Court based on brilliant Supreme Court advocacy by lawyers.

That's not true.

The greatest civil rights victories were won not by lawyers, but by the individuals whose stories those lawyers were privileged to tell.

By the time this case got to court everyone knew the story of DACA, and Luis was the one who really choreographed that.

He was that story too.

[light palpitating music] - [Chief Justice] You'll hear argument first this morning in case 18587.

Mr. Olson?

- Thank you Mr. Chief Justice, and may it please the court.

The decision... Luis is the first DACA recipient ever to be a member of the Supreme Court bar.

To have him sitting next to me in that court was a statement to me and it was a statement to the justices and it was a statement t everyone else that was watching or listening to that argument that this is what this case is all about.

The government's termination of DACA triggered abrupt, tangible, adverse consequences and substantial disruptions in the lives of 700,000 individuals, their families, employers, communities, and armed forces.

- [Chief Justice] Do you agree that the executive has the legal authority to rescind DACA?

- [Mr. Olson] Yes.

- [Supreme Court Justice] The current president telling DACA-eligible people that they were safe under him and that he would find a way to keep them here, and instead he's done this and that I think has something to be considered before you rescind a policy.

Not just saying, I'll give you six months to do it to destroy your lives.

[crowd cheering] [crowd chanting] Say it loud, say it clear!

- The stakes couldn't be higher for not just the 700,000 DACA recipients, but the communities, we're talking about millions of people, billions of dollars of impact in the economy.

I'm hoping that Congress really hears the roars of the community.

We have thousands of people here and this is really what made DACA exist.

[crowd cheering] The activism leads and then the law follows.
