The retirements of Hugo Black and John Marshall Harlan II created two Supreme Court vacancies in late 1971. One of Nixon's nominees, corporate attorney Lewis F. Powell Jr., was easily confirmed. Nixon's other 1971 Supreme Court nominee, Assistant Attorney General William Rehnquist, faced significant resistance from liberal Senators, but he was ultimately confirmed. Burger, Powell, and Rehnquist all compiled a conservative voting record on the Court, while Blackmun moved to the left during his tenure. Rehnquist would later succeed Burger as chief justice in 1986. Nixon appointed a total of 231 federal judges, surpassing the previous record of 193 set by Franklin D. Roosevelt. In addition to his four Supreme Court appointments, Nixon appointed 46 judges to the United States Courts of Appeals, and 181 judges to the United States district courts.
