We are the American Civil Liberties Union:

Dear President-elect Trump:

In case you had any doubt, we are the American Civil Liberties Union. And we're not moving to Canada.

So, rest assured that when you target immigrants, dissidents, and your political opponents – we will challenge you in the courts, at state legislatures, and in the streets.

Surely, you remember the landmark lawsuits we won against you on family separation, the U.S. Census, and immigrants' rights – some of which were decided by judges you appointed.

During your last presidency, we brought 434 legal actions, including 250 lawsuits against your administration's anti-civil liberties agenda.

We also mobilized the power of our more than 1 million card-carrying members into the streets, at airports, and in state capitals.

We've developed a comprehensive roadmap to defend our rights beginning on day one. We're not new to this.

At the ACLU, we play the long game. We've been around for 105 years and seen 19 presidents come and go.

That's why any attempt to roll back the nation's civil liberties on our watch will be hard fought and met with the full power of our resistance.

Steadfast and determined to make ours a more perfect union, we remain,

The ACLU
