Bush's top political advisor a traitor to the state?

So apparently Karl Rove (R-Hades), Bush's top political and policy advisor, is perhaps the one behind the leaking to the press of Valerie Plame's role in the CIA. In case you haven't been keeping up with this one, the story basically goes like this:

Joe Wilson, a diplomat with a long history in foreign service, was tasked to investigate claims that Saddam Hussein had attempted to purchase "yellowcake" uranium from Africa. In the course of his investigation, he discovered that the documents that were the foundation of this claim were poorly-done forgeries, and that there existed no evidence to back up this claim. The Bush administration, in trying to make a case to invade Iraq, quoted this forged evidence as gospel, claiming that Hussein was close to creating a nuclear weapon. Joe Wilson publicly disagreed with this claim, saying that it had already been debunked and that he was one of the ones responsible for debunking it.

So the Bush administration, in payback and an attempt to discredit him, leaks to certain members of the media that Joe Wilson's wife, Valerie Plame, is an undercover CIA agent in charge of monitoring weapons of mass destruction on an international scale.

Read that again, because outing an undercover CIA agent is not only illegal, it is also a betrayal of national security and possibly High Treason.

And apparently the person behind this leak is none other than Bush's right hand man, Karl Rove. Not only does he need to be held responsible for his actions, but there needs to be an immediate investigation called to see if this goes any farther up the chain. Was this the act of a renegade aide, or was Rove ordered to leak this information by Bush himself? Since when does a political aide get the security clearance necessary to even know this information about undercover CIA agents? Who was the one to give Rove the information?
