Since the excuse that Rove got Plame’s identity from a reporter, rumors have been swirling about whether it was Judy Miller, the New York Times reporter in jail for refusing to reveal her source, was the one who told Rove her identity. The theory goes that she’s refusing to reveal her source not because of principle, but because she was the one that started the scandal.

(To be fair, if this story is true, there’s still someone who leaked Plame’s identity to her. And this doesn’t get Rove and Libby off the hook either.)
