Fifteen states and the District of Columbia sued the federal government Wednesday seeking to block President Trump’s plan to end DACA—the Deferred Action for Childhood Arrivals program, which gives nearly 800,000 young immigrants permission to live and work in the United States. Among those pressing the suit is New York Attorney General Eric Schneiderman.

Attorney General Eric Schneiderman: “We understand what’s going on in Washington. And we know that when bullies step up, you have to step to them and step to them quickly. And that’s what we’re here to do today. … By definition, DREAMers play by the rules. DREAMers work hard. DREAMers pay taxes. For most, America is the only home they’ve ever known. They deserve to stay here.”

Trump’s cancellation of DACA, which was announced Tuesday by Attorney General Jeff Sessions, set off mass protests in cities around the U.S. In Washington, D.C., Wednesday, activists outside the Department of Justice building toppled a Confederate monument-style effigy of Jeff Sessions perched atop a cardboard pedestal labeled “Living Monument of White Supremacy.”
