The White House says Monday’s admission by CBS News raises some "serious questions."
CBS has acknowledged it can't vouch for documents used in a story questioning President Bush's National Guard service. The network says a former Texas Air National Guard official who was used as a source had misled a producer about where he got the documents used in the story.
White House press secretary Scott McClellan says the CBS statement admits for the first time those documents "were likely forged."
McClellan says there are now questions that need to be answered about the source, Bill Burkett, who he says has reportedly had senior level contacts with the John Kerry campaign.
CBS has said it will commission an independent panel to investigate the issue.
