Wells' opening said that Libby felt like a fall guy for the WH because Rove had been cleared but they balked at clearing Libby when he asked McClellan and Card so he (Libby) went to Cheney. It's all consistant and not contradictory.
Incidentally, it does not mean the WH was making Libby a fall guy, but that he felt that way at that time due to what I outlined above. Cheney defended Libby and wrote that note and McClellan then did make the requested statement.
"Felt like a fall guy." See, these kinds of mini-distinctions are absolutely lost on jurors, who hear, "The White House did it." You have confirmed my view that it was not a good defense.
