Labor leaders on Tuesday urged their members to back Democrats on the American Dream and Promise Act, the bill to grant a pathway to citizenship for the so-called “Dreamers” who arrived in the U.S. illegally as children.

“It is long past due that all members of Congress work together to immediately pass legislation that will give Temporary Protected Status and Deferred Action for Childhood Arrivals recipients a pathway to citizenship,” AFL-CIO President Richard Trumka said in a message to members Tuesday, after Democratic leaders introduced the legislation.
