Following up on our most recent post on Rathergate and CBS's planned statement, here are the details:

CBS News Anchor Dan Rather, the reporter of the original story, apologized. In a statement, CBS said former Texas Guard official Bill Burkett "has acknowledged that he provided the now-disputed documents" and "admits that he deliberately misled the CBS News producer working on the report, giving her a false account of the documents' origins to protect a promise of confidentiality to the actual source." The network did not say the memoranda — purportedly written by one of Mr. Bush's National Guard commanders — were forgeries. But the network did say it could not authenticate the documents and that it should not have reported them.

"Based on what we now know, CBS News cannot prove that the documents are authentic, which is the only acceptable journalistic standard to justify using them in the report," said the statement by CBS News President Andrew Heyward. "We should not have used them. That was a mistake, which we deeply regret."
