On Plame and Rove

David Corn jumps the gun on Newsweek's expose tomorrow apparently 'nailing' Rove as Miller's source. Though this much we already knew. As for new information... ? Per Corn, Newsweek's piece will make the claim that "Rove--prior to the publication of the Bob Novak column that first publicly disclosed Valerie Wilson/Plame as a CIA official--told Cooper that former Ambassador Joseph Wilson's wife apparently worked at the CIA and was involved in Joseph Wilson's now-controversial trip to Niger."
