Brit Hume talked about this yesterday. He said that Karl Rove had signed a release "before" so he (Hume) didn't think that the one that had just been signed would have been from Rove. It was speculation on Brit's part, but he made sense. This article doesn't contradict Brit's observation.
I heard Brit say that too and me thinks this is nothing but a knee jerk fantasy by the NY Slimes doing any and everything to smear Karl Rove. I do hope they'll be made to look incompetent and foolish once again.
Yesterday Rove's attorney denied that Rove was the person referenced by Cooper.
I doubt Cooper's "express, personal release" was signed, or that it was even a document. More likely it's a fairy tale, designed to cast further suspicion on Rove and/or the administration.
This whole case is about as clear as mud, and the MSM likes it just fine that way.
It appears the reporters did not rely on the earlier, formal releases. They knew everyone in the government was made to sign form releases. So it still could be Rove.
