Bob Woodruff leaves the hospital -- UPDATE

ABC News anchor Bob Woodruff was released from a military hospital today, six weeks after being seriously injured by a roadside bomb in Iraq. He suffered injuries to his neck, head, face, and chest and will requires many more months of rehabilitation, first in a private facility and then at his home. When he was released, doctors say he was laughing and joking with family and staff. Doug Vogt, the ABC cameraman also injured in the explosion, was released from the hospital in February.

ABC News has said that Woodruff is welcome to return to the anchor chair when he is ready. In the meantime, Diane Sawyer and Charlie Gibson have been subbing for him. ABC will dedicate Monday's entire episode of World News Tonight to the third anniversary of the Iraq war.
