The man who jumped the White House fence, sprinted across the lawn and entered through the unlocked front door made it much further into the building than previously reported.

Omar Gonzalez – who was carrying a knife – allegedly overpowered a Secret Service agent and reached the executive mansion’s East Room, where he was tackled by another agent at the door to the Green Room, eventually being taken into custody.

On Special Report this evening, Bret Baier spoke to Ed Henry, who said that these new revelations about the Sept. 19 incident will "further embarrass the Secret Service."

Henry added that there was a significant amount of wrestling and struggling inside the White House to subdue Gonzalez.

Henry noted that this breach - combined with a 2011 incident in which gunshots were fired at the White House, and the Secret Service was less than forthcoming with details - has many questioning the agency.

All of this unfolds just hours before Secret Service Director Julia Pierson faces a grilling tomorrow when the House Oversight and Government Reform Committee convenes for a hearing on these many security issues and what is being done to ensure the president and first lady are safe. reported:

An alarm box near the front entrance of the White House designed to alert guards to an intruder had been muted at what officers believed was a request of the usher's office, an official told The Washington Post.

An officer posted inside the front door appeared to be delayed in learning that Gonzalez was about to burst through, according to the Post. Officers are trained to immediately lock the front door once an intruder is spotted on the grounds.

Previously, the Secret Service had claimed that Gonzalez was intercepted shortly after he breached the front door at the North Portico.

Secret Service spokeswoman Nicole Mainor told Fox News that the agency would not comment on the revelations, citing the ongoing investigation.
