President Barack Obama on Thursday announced broad executive action on immigration policy, offering temporary relief from deportation to millions of undocumented migrants and giving them a chance to "get right with the law," NBC News reported. "We're going to keep focusing enforcement resources on actual threats to our security. Felons, not families. Criminals, not children. Gang members, not a mother who's working hard to provide for her kids," Obama said in a speech to the nation. The plan will allow as many as five million undocumented immigrants to stay in the U.S., including the undocumented parents of children born here. Crowds of immigration reform advocates rallied outside the White House during the president's address. Republicans, calling the executive order a constitutional overreach and a largely political maneuver, are vowing to fight the executive action.
