*UPDATE* Newsweek also claims that Rove was the one, though they weren't the first. Guardian reporter Julian Borger also claimed that Rove was the one (RealPlayer) way back in 2003. Numerous reporters and journalists in Washington have apparently known Rove was the source of the leaks for quite some time, but didn't reveal this information, in order to protect the right of U.S. journalists not to reveal their sources. A U.S. reporter trying to release a story claiming Rove was the one would've most certainly been prevented from going forward with their story, and would've faced potential ostracism. Borger, a Brit, had no such qualms going forward with this information.
So much for the White House saying "He wasn't involved. The President knows he wasn't involved."
Bushit. As Scott McClellan said in the same press conference, "common sense kind of tells you that if there's a covert CIA agent, then a limited number of people should have access to that information." ... and Karl Rove was not one of these people. Who was? How about Cheney? ... or Bolton? Or both.
Time to start warming up the tar...
