As between Libby and reporters? Not really. The indictment depends on and is driven by Libby having knowledge of Plame independently from conversations with reporters.
The "faulty memory" problem that gets Libby off the charge would be the memory of investigators. Libby might assert that teh investigators forgot or withheld that Libby DID tell them that he (Libby) checked Plame's status at CIA.
But his direct testimony (in the indictlment) leads away from asserting that fact.
Investigators have independent evidence that Libby checked with CIA. That is, independent of conversations with reporters.
I would not place a big wager on his conviction.
I give it better than even odds -if- the case goes to trial. I don't see the charge being dropped, but a plea bargain is possible.
No. That is true of the counts respecting Russert, but not the counts involving Miller and Cooper. As to the odds, ruch to Tradesports and place your money. Last I checked the odds were at 48%.(Odds of Rove indictment by March 31 were 16%).
