Take a look at this post by Byron York at the The Corner. First, folks he's talking to agree that the case against Libby looks very strong. Set aside all the blah-blah about whether he should be indicting people for perjury if he couldn't get him on the underlying crime, etc. He went for a perjury and obstruction indictment. And it really looks like he has him. Second, he floats speculation that Tim Russert may have had some definitive record of his conversation with Libby, i.e., audio tapes, rather than simply a different recollection than Libby's.
