WASHINGTON (AP) - Secret Service Director Julia Pierson resigns amid recent White House security breach.
Homeland Security Secretary Jeh Johnson said Wednesday that Pierson offered her resignation, and he accepted it.
The move came one day after her appearance before the House Oversight and Government Reform Committee in a congressional hearing focused on recent security lapses at the White House.
Pierson had worked at the Secret Service for 30 years.
Accused White House fence-jumper Omar Gonzalez has pleaded not guilty to charges that he ran into the presidential mansion while carrying a knife.
Gonzalez's lawyer entered the plea on behalf of his client in a proceeding today before a U.S. magistrate judge.
A three-count federal grand jury indictment issued Tuesday accuses Gonzalez of unlawfully entering a restricted building while carrying a deadly weapon, a federal charge.
