65th United States Congress

The 65th 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 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 1910 United States census.

The Senate maintained a Democratic majority. In the House, the Republicans had actually won a plurality, but as the Progressives and Socialist Representative Meyer London caucused with the Democrats, this gave them the operational majority of the nearly evenly divided chamber, thus giving the Democrats full control of Congress, and along with President Wilson maintaining an overall federal government trifecta.
