The 77th 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, 1941, to January 3, 1943, during the ninth and tenth years of Franklin D. Roosevelt's presidency. The apportionment of seats in the House of Representatives was based on the 1930 United States census. Both chambers maintained a Democratic majority - with the Senate being a supermajority. With the reelection of President Franklin D. Roosevelt to a then record third term, the Democrats maintained an overall federal government trifecta. This was the first Congress to have more than one Senate president (John Garner and Henry Wallace) due to the passage of the 20th Amendment in 1933.
