White House-AP -- Officials at the White House are already looking over the early evidence on just what happened to the Space Shuttle Columbia Saturday.
They gathered Sunday in the Situation Room to look at what's known so far about Saturday's breakup of the shuttle.
The head of the White House Office of Science and Technology Policy says the idea is to get the forensic evidence and the debris -- and "get the experts working on it." John Marburger says they can then come up with theories on what happened.
Aides are briefing President Bush, who returned Saturday from Camp David when word came about the shuttle accident.
