STATEMENT FROM DAN RATHER:

Last week, amid increasing questions about the authenticity of documents used in support of a 60 MINUTES WEDNESDAY story about President Bush's time in the Texas Air National Guard, CBS News vowed to re-examine the documents in question—and their source—vigorously. And we promised that we would let the American public know what this examination turned up, whatever the outcome.

Now, after extensive additional interviews, I no longer have the confidence in these documents that would allow us to continue vouching for them journalistically. I find we have been misled on the key question of how our source for the documents came into possession of these papers. That, combined with some of the questions that have been raised in public and in the press, leads me to a point where—if I knew then what I know now—I would not have gone ahead with the story as it was aired, and I certainly would not have used the documents in question.

But we did use the documents. We made a mistake in judgment, and for that I am sorry. It was an error that was made, however, in good faith and in the spirit of trying to carry on a CBS News tradition of investigative reporting without fear or favoritism.

Please know that nothing is more important to us than people's trust in our ability and our commitment to report fairly and truthfully.

Then there is this:

CBS Regrets Bush Memos Story

(CBS/AP) CBS News said Monday it cannot prove the authenticity of documents used in a 60 Minutes story about President Bush's National Guard service and that airing the story was a "mistake" that CBS regretted.

CBS News Anchor Dan Rather, the reporter of the original story, apologized.

CBS claimed a source had misled the network on the documents' origins.

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.

So Dan Rather calls a guy with a history of mental illness and a grudge against Bush "unimpeachable."

Time for Dan to say good night.

In the statement, CBS said: "Burkett originally said he obtained the documents from another former Guardsman. Now he says he got them from a different source whose connection to the documents and identity CBS News has been unable to verify to this point."

WHO WHO WHO?

Update: Amazingly if you read the release, they are still trying to sell the story!
