Nixon took office with one pending vacancy, as the Senate had rejected President Johnson's nomination of Associate Justice Abe Fortas to succeed retiring Chief Justice Earl Warren. Months after taking office, Nixon nominated federal appellate judge Warren E. Burger to succeed Warren, and the Senate quickly confirmed Burger. To replace Fortas, Nixon successively nominated two Southern federal appellate judges, Clement Haynsworth and G. Harrold Carswell, but both were rejected by the Senate. Nixon then nominated federal appellate judge Harry Blackmun, who was confirmed by the Senate in 1970. In December 1969, Nixon somewhat reluctantly signed the Tax Reform Act of 1969 despite its inflationary provisions; the act established the alternative minimum tax, which applied to wealthy individuals who used deductions to limit their tax liabilities. Though the FAP passed the House, the bill died in the Senate Finance Committee in May 1970.
