Tribe testified at length during the Senate confirmation hearings in 1987 about the Robert Bork Supreme Court nomination, arguing that Bork's stand on the limitation of rights in the Constitution would be unique in the history of the Court. His participation in the hearings raised his profile outside of the legal realm and he became a target of right-wing critics. His phone was later found to have been wiretapped, but it was never discovered who had placed the device or why.
