perjury shmerjury. Lying to investigators is only bad if Clinton does it.
How did you determine Libby lied?
IF Libby committed perjury he will have to face the legal consequences (and he should). Whatever the story of the Libby's testimony turns out to be, that will not change the fact that this is a sham investigation driven by a ludicrous effort by MSM reporters and Demagogues to concoct a case against the administration that never should have been taken seriously in the first place (Joe Wilson's asinine and incoherent recitations of nonsense, etc.).
Libby is responsible for any legal consequences he may have incurred IF he gave any untruthful testimony, but that should not distract from the far more important issue: the shameless charlatans who concocted and sustained the whole ludicrous "Niger uranium" story in the media.
