Addington, along with other officials, was mentioned by title in I. Lewis "Scooter" Libby Jr.'s indictment for five felony charges related to the Plame affair, regarding the leak of the identity of a CIA officer, and he testified at the Libby trial. A PBS "Frontline" documentary "Cheney's Law" broadcast on October 16, 2007 detailed Addington's key role in Bush administration policy making, and noted that he declined to be interviewed regarding his thoughts on the limits of executive privilege. On June 26, 2008, Addington appeared to testify under subpoena from the House Judiciary Committee along with former Justice Department attorney John Yoo in a contentious hearing on detainee treatment, interrogation methods and the extent of executive branch authority. This testimony was Addington's only public statement during his eight years as Cheney's vice presidential counsel and chief of staff.
