Joe testified- there is no record of Valerie testifying.

From this list, I have a feeling that Novak source is Richard Armitage.
Joe Wilson's Lies, A Timeline - Who Forged the Documents? (Vanity)
A plausible case for a rogue CIA/French conspiracy against the President and his adminstration.
My own take on this affair is a bit more mundane: Wilson gets involved in the anti-war crowd and Kerry's camapaign. Little wifey tells Joe about goings on at work. Joe uses these tidbits in talks to make himself sound more important. Novak writes article noting that Joe's wife is with the CIA. Joe gets mightily worried. To leak secrets from the CIA is a big no-no for both little wife and prospective Kerry Sec State Joe W. Joe goes to attack. MSM and CIA follow suit.
Joe testified! Oh boy - that's encouraging! Hope he lied under oath!!
