The US Secret Service chief has stepped-up security outside the White House after a man with a knife who jumped the fence made it into the presidential residence before being apprehended, officials said.
President Barack Obama insisted he still has confidence in the agency's ability to protect him and his family, as Secret Service director Julia Pierson ordered enhanced patrols and surveillance along the North Fence of the compound after the incident on Friday evening.
The scare triggered a rare evacuation of the White House as well as renewed scrutiny of the Secret Service. The agency said Pierson had also ordered a comprehensive review of what happened. "The president has full confidence in the Secret Service and is grateful to the men and women who day in and day out protect himself, his family and the White House," said White House spokesman Frank Benenati. He said the White House expected Pierson's review to be conducted "with the same professionalism and commitment to duty that we and the American people expect from the US Secret Service".
The presidential vote of confidence came as the agency sought to dispel growing concerns about security at the White House, one of the most heavily protected buildings in the world.
Another man was arrested on Saturday outside the White House in an unrelated event.
