AG Gonzales is testifying before congress at present — it's live on CSPAN. It's not pretty. His position is that he can't testify about anything on which he's recused. And he can't recall much else — including how much attention he paid to approving a death penalty request. Were it not for the cavalier way in which he and his boss treated death warrants in Texas, this would not be credible. But unfortunately, it might be the truth.
Senator Specter did not look happy — but will this actually spur him to support a call for impeachment of Gonzales? Nothing less will do.
