U.S. lawmakers scolded the head of the U.S. Secret Service on Tuesday over a security breach that allowed a knife-wielding intruder to run deep into the White House, and Director Julia Pierson promised them it would never happen again.
Pierson acknowledged the agency charged with protecting the president had failed on Sept. 19 when it allowed a man to jump the fence at the home of the president of the United States, burst through the front door and run into the East Room, which is used for events and receptions.
"This is unacceptable and I take full responsibility," she told a U.S. House of Representatives committee investigating the incident, promising a complete review of agency procedures.
