Senator Richard Burr (R-NC) walks to the Senate Chamber to vote on legislation for funding the Department of Homeland Security on Capitol Hill in Washington March 2, 2015. Three days after lawmakers narrowly avoided a partial shutdown of the Department of Homeland Security in a dispute over immigration reforms, the Senate voted 58-31 to send a "clean" full-year funding bill back to the House.
