Updated: Executive Office Building Fire
The Eisenhower Executive Office Building (the big grey building directly west of the White House) caught on fire this morning. The Washington Post reports that it apparently started on the 3rd floor.
UPDATE: WTOP is now reporting that the fire has been contained. About 1,700 people had to be evacuated, but Cheney (who was right next door at the time) didn't even get a lungful. [Washington Post, WTOP]
