A coalition of 16 states have filed a federal lawsuit challenging President Trump’s national emergency declaration, claiming it is unconstitutional. California Attorney General Xavier Becerra filed the suit on behalf of the group Monday. He says Trump’s move violates Congress’s power to control the budget and is a misuse of public money.

Also on Monday, President’s Day, protesters took to the streets around the country to denounce Trump’s emergency declaration. This is Diallo Brooks of People for the American Way speaking at a rally in Washington, D.C.

Diallo Brooks: “And we will fight at every turn for justice for everyone, no matter what you look like or where you come from. We will fight, and we will stand up, and we will make our voices heard. Thank you.”
