That was rhetorical, right? (you know the answer)
Matthews wife was news anchor at channel 7 in DC for over 20 years, and she and Matthews were in Washington Society, so I can't believe they had never heard of Joe and Valerie Plame Wilson! Those two egotists (the Wilsons), I think, would want to be noticed wherever and whenever they could.
I do believe Andrea Mitchell spoke the truth when she said 'reporters knew Wilson's wife worked at the CIA', and I will not be surprised if it is revealed, but denied, that Tim Russert did, in fact, know of and about Valerie Plame. His wife is an investigative reporter with Vanity Fair and other publications, so they move in the "right" social circles in DC also. I can't believe they didn't take a look at the Wilson's when Joe's article that started all of this was published!
