Atrios discovers a Cheney vs Cheney moment regarding Joesph Wilson: " Cheney: No. I dont know Joe Wilson." Mr. Libby's notes indicate that Mr. Cheney had gotten his information about Ms. Wilson from George J. Tenet."
Jeralyn says: Shorter version: Libby lied to protect Cheney, who may or may not have needed him to lie, and now Libby is hoisted on his own petard.
