Joe is correct on this. Libby was supposed to serve time but President Bush commuted the sentence and Libby remained free. The original conviction still stands though.
As it should. That cowardly game playing by the Bush Administration made me sick. All somebody needed to do was stand up and say, "Joe Wilson is a fraud. His wife, Valerie Plame, who works for the CIA, apparently colluded with other Democrat fixers at CIA and State to send her husband to Nigeria for cocktails with fellow low-level diplomats so he could come back and report that he 'found no evidence', etc. We have asked the FBI to investigate these shenanigans and report back if they find that any laws were violated."
But no... they all had to play coy.
