Julia Pierson

The 23-year-old Maryland man who climbed over the White House fence Wednesday night has been charged with felonies for assaulting two police dogs and making threats, the Secret Service said Thursday.

A government investigation Wednesday criticized a bizarre Secret Service assignment that pulled agents from their duty near the White House and sent them to the rural Maryland home of a headquarters employee embroiled in a personal dispute with a neighbor.

Two years after a prostitution scandal rocked the Secret Service, a Republican congressman renewed allegations Thursday about possible involvement by a White House volunteer and said he smelled efforts to cover it up.

Julia Pierson, director of the Secret Service, resigned on Wednesday after a series of serious safety breaches dating back to 2011 were publicly revealed. Pierson was in charge of the agency responsible for protecting the president and the first family for about 18 months.

Secret Service Director Julia Pierson stayed impassive under a barrage of criticism at a congressional hearing on the agency’s shortcomings on Tuesday. The only signs that she was unsettled were a couple of mangled words and a misstatement, a big one.
