Potential witnesses in the upcoming criminal trial of I. Lewis "Scooter" Libby, as referenced in court papers by Libby's lawyers. The trial is scheduled for January:

—Richard Armitage, former deputy secretary of state

—Ari Fleischer, former White House press secretary

—Marc Grossman, former undersecretary of state for political affairs

—Stephen Hadley, the president's national security adviser

—Colin Power, the former secretary of state

—Karl Rove, the deputy White House chief of staff

—George Tenet, the former CIA director

—Joseph Wilson, a former U.S. ambassador

—Valerie Plame Wilson

—A CIA briefer referred to in the indictment, though not by name. The court papers identify the person as "Craig Schmall, Peter Clement or Matt Barrett." The indictment says that on June 14, 2003, Libby expressed displeasure to the briefer that CIA officials were making comments to reporters that were critical of the vice president's office and discussed with the briefer Wilson and Plame in the context of Wilson's trip in 2002 to the African nation of Niger.

—A senior CIA official referred to in the indictment, "who may be either Robert Grenier or John McLaughlin." Grenier at one time was the CIA's top counterterrorism officer. McLaughlin was deputy director of the CIA. The indictment says Libby spoke to the official on June 11, 2003 about the circumstances of Wilson's trip to Africa and was told that Wilson's wife worked at the CIA and was believed responsible for sending him on the trip.

—Former CIA spokesman Bill Harlow. Libby's court filing says the defense team believes that Harlow is the unidentified government official in the indictment who told Catherine Martin, assistant to the vice president for public affairs, that Wilson's wife worked at the CIA and advised Libby of it.
