Julia Pierson, the embattled director of the U.S. Secret Service, resigned Wednesday amid embarrassing new revelations of breaches to the protective cordon around President Barack Obama.
Pierson, who had been in the job only a year, submitted her resignation to Homeland Security Secretary Jeh Johnson, who accepted, Johnson said in a statement. The move comes a day after a contentious hearing on Capitol Hill over how an armed man managed to jump the White House fence and enter the Executive Mansion last month before being apprehended by officers, and hours after congressional leaders, including House Minority Leader Nancy Pelosi, called for her resignation.
Johnson named Joseph Clancy, a retired agent who previously led the agency’s Presidential Protective Division, as the interim acting director of the Secret Service, while taking the ongoing review of the Sept. 19 fence-jumping incident out of the hands of the agency. Deputy Secretary of Homeland Security Alejandro Mayorkas and the department’s general counsel will now oversee the inquiry, with its report due on Nov. 1.
Johnson is also appointing a panel of outside experts, yet to be named, to conduct an independent outside investigation of security at the White House compound, as well as broader issues that have plagued the Secret Service in recent months.
