So Libby is probably going to be indicted for misleading a grand jury. This is, of course, a very different charge than leaking the identity of a covert agent. At this point no one on the prosecution has alleged that Libby had anything to do with the leak, merely that he deliberately neglected to mention a conversation he had with someone involved (I forget which conversation is the one that he omitted from his previous testimony). At any rate, there is yet no actual evidence that a leak occurred.
