On May 12, 2006, U.S. Rep John Conyers (Dem, Michigan) sent a formal request to U.S. Attorney Alberto Gonzales, asking him to name a special prosecutor to investigate the 2002 phone jamming. Conyers, the senior Democrat on the House Judiciary Committee, said an independent counsel was necessary to investigate allegations that White House officials may have been involved in the scheme, pointing out that the US Department of Justice "appears not to be reviewing the extensive contacts between the plotters of the phone jamming and high-level Republican officials."[59]
