Washington fire officials say investigators are working to determine the cause of this morning's fire at the Eisenhower Executive Office Building near the White House.
A D.C. fire department spokesman says there are no reports of injuries, although one man broke a fifth-floor window to escape from the smoke and had to be rescued from a ledge.
The fire itself appeared to be located in Vice President Cheney's suite of ceremonial offices on the second floor of the building.
Cheney and President Bush were across the street in the West Wing of the White House when the blaze broke out.
The building was evacuated as a precaution, but the blaze appeared to be under control within an hour.
