Dick Cheney, today on Face the Nation, when asked about the U.S. Attorney purge:

Well, as vice president, I don't know anything about the particular problem you're talking about. I mean, it took place inside the Justice Department. The one who needs to answer to that and lay out on the record the specifics of what transpired is the attorney general, and he'll do so.

Alberto Gonzales is, as John Ehrlichman said, "twisting slowly, slowly in the wind."
