What can you say about a video that speaks so clearly for itself? If you don't believe Pelosi is lying through her teeth at this point, you never will. Her story has changed repeatedly, and the one she's telling now makes no sense. You get the feeling that about halfway through her appearance, she suddenly realizes that the press isn't going to simply reprint her statement; they're going to evaluate it against the facts. And then she's lost.
At this point, the best parallels I can conjure are Barry Bonds and Roger Clemens. Are there any better examples of unrepentant liars who ask you to believe their words, rather than everyone else, and your own good sense?
How does she extricate herself from this?
