On July 1, 1987, President Ronald Reagan nominated Judge Robert Bork for Associate Justice of the Supreme Court of the United States, to succeed Lewis F. Powell Jr., who had earlier announced his retirement. At the time of his nomination, Bork was a judge on the United States Court of Appeals for the District of Columbia Circuit, a position to which he had been appointed by President Reagan in 1982.
Bork's nomination precipitated contentious debate. Opposition to his nomination centered on his perceived willingness to roll back the civil rights rulings of the Warren and Burger courts, and his role in the Saturday Night Massacre during the Watergate scandal. On October 23, 1987, the United States Senate rejected Robert Bork's nomination to the Supreme Court by a roll-call vote of 42–58. This is the most recent Supreme Court nomination to be rejected by vote of the Senate.
