That is factually incorrect.
Actually it isn't.
You can quibble about plausible deniability..but it's reasonable to assume something of this magnitude came directly from the White House.
No, not really.
Let's review, one more time.
Robert Novak asks Richard Armitage how the hell a HOUSE HUSBAND could have possibly been sent on a secret mission by the CIA. Richard Armitage mutters, "Well, his wife is an analyst at the CIA". He calls Karl Rove, and asks if that's true. Rove says, "Yeah, I heard that." So far, nothing illegal, because she's an analyst, not an operative. Also, neither of these guys mentioned her by name.
So Novak opens up a copy of "WHo's Who in America" and finds out former ambassador and current house husband Joe Wilson is married to Valerie Plame, who works at the CIA. In short, the CIA was cleverly listing the names of their super secret spies in a publicly available book. Wow, that's clever.

Incidently, one more point about Joe Wilson. In February, 2003, he authored an article entitled "A big cat with nothing to lose" where he claimed we shouldn't attack Iraq because Saddam HAD weapons of mass destuction.

This was only a few weeks after Bush had made the speech where Wilson "knew" he was lying about WMD's.
