A new Deep Throat?Steve Clemons does some good reporting and makes what seems to me a sound analytic point:
If, in fact, neither Dana Priest nor Mike Allen was subpoenaed before the Plame grand jury, that creates a strong inference that the prosecutor already knew whatever they could have told him. In particular, the prosecutor must know the identity of their source for the 2 x 6 assertion (that two senior administration officials had told six reporters about Plame's identity) and that source must have told the prosecutor substantially what he or she told Priest and Allen.
It seemed to me at the time that Priest and Allen's original story strongly hinted that Rove was one of the two bad guys. As others have noted, the Libby indictment identifies Rove as "official A," and in the history of Fitzgerald's corruption cases "official A" usually gets indicted eventually.
