The 93rd United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, D.C., from January 3, 1973, to January 3, 1975, during the last 18 months of Richard Nixon's presidency, and the first 6 months of Gerald Ford's. This Congress was the first (and, to date, only) Congress with more than two Senate presidents (in this case, three). After the resignation of Spiro Agnew, Gerald Ford was appointed under the authority of the newly ratified 25th Amendment. Ford became president the next year and Nelson Rockefeller was appointed in his place. The apportionment of seats in the House of Representatives was based on the 1970 United States census. Both chambers had a Democratic majority. This is the earliest Congress to feature a member of the 117th Congress, Representative Don Young (R-AK), who served until he died in 2022.
