The Sixty-fifth United States Congress met in Washington, DC from March 4, 1917, to March 4, 1919, during the fifth and sixth years of Woodrow Wilson's presidency. The apportionment of seats in this House of Representatives was based on the Thirteenth Census of the United States in 1910. The Senate had a Democratic majority, and the House had a Republican plurality but the Democrats remained in control with the support of the Progressives and Socialist Representative Meyer London.
