Woodward's statement does not change the facts of Libbey's indictment, but it certainly changes the chemistry. We now have two reporters -- one on camera and one under oath -- who have said they knew about Plame. This really starts to confirm Libbey's claim that many people in Washington knew.
Not only that, but you now have a situation where one WAPO reporter is directly contradicting another.
Can anyone spell reasonable doubt?
