At 9:00 p.m. Friday, the highest-level staffers will turn in their gear; and the West Wing will become a ghost town. Chief of Staff Josh Bolten, Counselor Ed Gillespie, and Press Secy Dana Perino are the senior staffers who will remain here, on standby. Monday is a federal holiday so the White House would be closed anyway. On Tuesday, Special Agent Donald White of the U.S. Secret Service will shadow President Bush, sit in the customary front 'shotgun' seat of the limousine, and guard the President until noon. At 12:01, Agent White steps over to a position behind Barack Obama.
