Here is the sequence of events:
Novak printed that Wilson's wife worked at the CIA. He did not name her, nor did he say in what capacity. He states that no one told him that she was undercover and he wouldn't have printed this had he known she was.
Novak told Rove about Plame.
Two days after Novak's article David Corn wrote an article in the Nation with all the inside information -- i.e. her name, her job, etc...
How did Corn get the info? He's a friend of Wilson's... connect the dots....he knew too much not to have received it from the horses' mouth....
There is a lot of similar dots to Judith Miller.
I think The Grand Jury needs to speak to David Corn and make him spill the beans or join Judith in jail.
Yes!! I just posted a reply to a message above before I read your post - I was talking about Cliff May's important article in The National Review

discussing how Joe Wilson (or a "cut out" person close to him he may have used to shield himself from legal repercussions) apparently prepped David Corn (left-wing hack with the socialist rag "The Nation") and Corn had a hit-piece just two days after Novack's column, decrying alleged White House dirty tricks and providing a remarkable amount of hero-worship of Joe Wilson:

Any freepers with real contacts and/or research skills to develop this story should really explore this angle, I think: Wilson probably shopped his story to various reporters, one way or another his wife's position was referred to (possibly by Wilson himself, or else one of his buddies), and the whole brouhaha against Rove and the White House has been an enormous distraction from the real culprits.
The entire controversy was stupid from the get-go. What kind of 'revenge' motive would lead a WH figure to think "gee, why don't I out Wilson's CIA wife to punish Wilson for being such a brave dissenter?" I've always thought that seemed like a very very unlikely way for someone like Rove to think and act, but it fits perfectly with a shallow opportunistic grandstanding wannabe like Wilson who is imaginging the book he's going to write as he goes about trashing the administration.
