When President Clinton's pardon of Marc Rich stirred its own controversy back in 2001, former President Clinton took the forthright step of waiving Executive Privilege and permitting some of his closest aides to testify about the facts of the matter. On March 1, 2001, President Clinton's former Chief of Staff John Podesta, his former Counsel Beth Nolan, and one of his closest counselors Bruce Lindsay testified before Chairman Burton's House Government Reform Committee on this matter. As Chairman Burton acknowledged in his opening statement: "We asked the president not to claim executive privilege so his aides could testify, and he's done that, and that's a positive step."

I'm starting to like the fact that Libby's clemency is being compared with Clinton's pardons.
