Now that Richard Armitage has been exposed by the Michael Isikoff and David Corn, Bob Novak finally tells his version of how he learned about Valerie Plame, and contradicts Richard Armitage.

I want to set the record straight based on firsthand knowledge.

First, Armitage did not, as he now indicates, merely pass on something he had heard and that he ‘‘thought’’ might be so. Rather, he identified to me the CIA division where Mrs. Wilson worked, and said flatly that she recommended the mission to Niger by her husband, former Amb. Joseph Wilson.

Second, Armitage did not slip me this information as idle chitchat, as he now suggests. He made clear he considered it especially suited for my column.

And Joe Wilson and Valerie have changed their minds, and are adding Richard Armitage as a defendant in the lawsuit.
