With the Capitol in the background, transportation maintenance workers check their traffic light system after widespread power outages cause traffic lights to go out and many of the buildings along the National Mall in Washington to shut down temporarily, Tuesday, April 7, 2015. Widespread power outages affected the White House, State Department, Capitol and other sites across Washington and its suburbs Tuesday afternoon — all because of an explosion at a power plant in southern Maryland, an official said.
