If the NYT story is true and Novak told Rove about Plame, then could Novak have also been Judy Miller's source? Maybe she's covering for Novak. It's clear to me that the bond between journalists is greater than any political allegiance... look at papers like the Wash Times writing editorials for a federal shield law to cover mostly liberal journalists.
I don't know.. just a thought. And maybe one that isn't even possible.
I'm sketchy about that source; I think Judith Miller is a source, but I'm just not sure to who: probably Scooter Libby, who then told Rove?
But she's covering for whoever told her -- or for the fact that she is the leaker.
