In a not-so-shocking development, Secret Service chief Julia Pierson has resigned, reports CNBC. The move comes amid withering criticism in the wake of high-profile security lapses involving President Obama. Homeland Security chief Jeh Johnson announced the resignation and said he was appointing Joseph Clancy to be interim director of the Secret Service, reports CNN. Clancy led the president's security team before his retirement three years ago. Pierson took over in March 2013 as the agency's first female director. “I salute her 30 years of distinguished service to the Secret Service and the nation,” said Johnson in his statement. He also promised a full review of the agency. (More Secret Service stories.)
