The Ninety-fifth 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, DC from January 3, 1977, to January 3, 1979, during the final weeks of the administration of U.S. President Gerald Ford and the first two years of the administration of U.S. President Jimmy Carter. The apportionment of seats in this House of Representatives was based on the Nineteenth Census of the United States in 1970. Both chambers had a Democratic majority. It was the first time either party held a filibuster-proof 60% super majority in both the Senate and House chambers since the 89th United States Congress in 1965, and last time until the 111th United States Congress in 2009. All three super majorities were Democratic party and also were accompanied by Democratic Presidents. As of 2020, this is the most recent Congress to approve an amendment (the unratified District of Columbia Voting Rights Amendment) to the Constitution.
