Fence-jumper ran through much of main floor of White House

WASHINGTON (Reuters) - The man who breached security at the White House this month raced through several rooms on the main floor, penetrating farther into the building than previously disclosed, a Republican congressman said on Monday.

Representative Jason Chaffetz, who chairs a House subcommittee on national security oversight, told CNN an alarm box near the front entrance had been muted, leaving interior personnel unaware of the intrusion before the suspect burst through the open front door.
