Secret Service Director Faces the Music Today

Secret Service Director Julia Pierson appeared before a House committee Tuesday after mounting disclosures about dramatic White House security breaches.

Pierson's appearance before the House Oversight and Government Reform Committee marked the director's first public statements about how an Army veteran managed to scale a perimeter fence on Sept. 19 and burst into the White House where he made it all the way to the mansion's East Room before he was stopped.The Washington Postreported Tuesday that it was an off-duty Secret Service agent who was leaving for the night who finally tackled him.
