Marcy Wheeler is all over this, see here, here, and here, and her conclusion, and mine, is that Cheney told people to out Valerie Plame as a covert operative in order to hurt her husband, Joe Wilson (the non-shouting one).

Now that the grand jury information is out, even mainstream sources, like CBS News, are making it clear that they know that Dick Cheney lied through his teeth to investigators, though it would be nice if they called him a liar, as opposed to being so oblique:

Vice President Dick Cheney told the FBI he had no idea who leaked to the news media that Valerie Plame, wife of a Bush administration critic, worked for the CIA.

An FBI summary of Cheney’s interview from 2004 reflects that the vice president had deep concern about Plame’s husband, Joseph Wilson, a former U.S. ambassador in Africa who said the administration had twisted prewar intelligence on Iraq.

…

The vice president said he probably discussed Wilson with Bush’s top political adviser, Karl Rove, but told the FBI he would not have talked to Rove about Wilson’s wife.

Cheney’s denials that he talked about Plame are among the few things in the lengthy interview with the FBI that Cheney appeared certain about. He repeatedly said he could not recall key events. Among them, he said he did not recall discussing Wilson’s wife with Libby before her CIA employment was publicly revealed by conservative columnist Robert Novak in mid-July 2003.

Evidence at Libby’s criminal trial showed that Cheney had told Libby about Wilson’s wife in mid-June 2003.

(emphasis mine)

Unfortunately, there is no appetite for pursuing actions that border on treason.

Unfortunately, we have to deal with the Washington, DC we have, not the Washington, DC you might want or wish to have at a later time.
