Time does not permit me to delve into this, so let me pose a puzzler - since Waxman is seeking DoJ files rather than Presidential and Vice-Presidential papers, surely this issue can be taken up in an Obama Administration. In which case I predict heartbreak on the left when President Barack decides to put institutional prerogatives ahead of lefty fantasies.
I CAN QUIT ANYTIME: Sorry, this will be cryptic and, for a while at least, relatively link free. However, the gist of the relevant timeline is that Cheney and Libby discussed Joe Wilson's wife in early June 2003. Libby then claimed to have forgotten that chat; he learned about Wilson's wife as if for the first time when Tim Russert told him about Wilson and wife on July 10 or 11, following the Joe Wilson op-ed but preceding the fateful Novak column. However, Libby had discussed Wilson's wife with Judy Miller on July 8, at a meeting where Cheney had authorized Libby to leak info from the National Intelligence Estimate on Iraq. Cheney and Libby also discussed what to tell reporters on Sat July 12, before Libby was asked about Wilson's wife by Matt Cooper of TIME.
And Fitzgerald introduced a copy of the Wilson op-ed marked up in Cheney's handwriting with a mention of Wilson's wife.
