Through TPM Muckracker, Murray Waas reports that:
Karl Rove was in fact columnist Robert Novak's source for learning Valerie Plame's identity, and that the two men, upon learning of a federal investigation, spoke and may have created a false cover story to hide the truth.

I think three words sums up how I feel about this:
Please be true.
