A U.S. Immigration and Customs Enforcement (ICE) agent waits as a group of undocumented men, not pictured, are deported to Mexico at the U.S.-Mexico border in San Diego, California, U.S., on Thursday, Feb. 26, 2015. The U.S. Department of Homeland Security is nearing a partial shutdown as the agency's funding is set to expire Friday -- something Senate Majority Leader Mitch McConnell had said wouldn't happen on his watch.
