A screen on the tv while the guy from Texans for truth was speaking said that he was a former leader of MoveOn.Org. and had other suspicious ties, as well.
All that is accurate. He is slimey, and intended to prepare and air advertisements that claimed Bush was seriously delinquent in some aspect of his National Guard commitment.
But I did read that the group is adamant that it has no connection with the CBS documents. I'm sure whoever prepared them would want to deny it, and their denial may be false. My gut (FWIW) tells me this group did not originate the forged documents.
Top of the hour radio news reports 1) CBS stands behind the accuracy of its 60 Minutes story and 2) the White House is "interested" in this story.
