The White House fence-jumper made it deeper into the White House than originally reported.
The intruder, Omar Gonzalez, jumped the fence, sprinted through the front door, overpowered one Secret Service officer and ran through much of the main floor before being apprehended, according to the Washington Post.
Earlier, officials said he was quickly detained at the White House main entrance.
An alarm box near the front entrance designed to alert guards to an intruder was muted — apparently at the request of the usher’s office, an unnamed Secret Service official told Washington Post.
After darting past a guard at the front, Gonzalez, who had a knife, went past the stairway that leads up to the first family’s living quarters. He then ran into the East Room, which is often used for receptions and or presidential addresses.
Gonzalez was then tackled by a counter-assault agent at the far southern end of the East Room. He had reached the doorway to the Green Room, a parlor overlooking the South Lawn, the sources said.
Agency spokesman Edwin Donovan said the office is not commenting due to an ongoing investigation of the incident.
The House Oversight and Government Reform Committee is set to have a hearing Tuesday to discuss a number of recent security lapses by the Secret Service.
