Here are the witnesses who are scheduled to testify this Wednesday for the House Judiciary Committee's hearing on Bush's commutation of Libby's sentence:
Ambassador Joseph Wilson
Roger Adams, US Department of Justice Pardon Attorney
Douglas A. Berman, William B. Saxbe Designated Professor of Law, Moritz College of Law, The Ohio State University
Tom Cochran, Assistant Federal Public Defender, Middle District of North Carolina (Attorney for Vincent Rita, Rita v. US)
David Rifkin, partner, Baker & Hostetler LLP, former Justice Department official during the Reagan and Bush Sr. administrations
"Congress must now look into presidential authority to grant clemency, and how such power may be abused. Taken to its extreme, and possibly in the case of the Libby clemency, the use of such authority could completely circumvent the law enforcement process and prevent credible efforts to investigate wrongdoing in the executive branch."
