115th United States Congress



The 115th United States Congress was a meeting of the legislative branch of the United States of America federal government, composed of the Senate and the House of Representatives. It met in Washington, D.C., from January 3, 2017, to January 3, 2019, during the final weeks of Barack Obama's presidency and the first two years of Donald Trump's presidency. The seats in the House were apportioned based on the 2010 United States census.

The Republican Party retained their majority in both the House and the Senate, and, with inauguration of Donald Trump on January 20, 2017, attained an overall federal government trifecta for the first time since the 109th Congress in 2005. This remains the last Congress to date in which the Republican Party held a trifecta.

Several political scientists described the legislative accomplishments of this Congress as modest, considering that both Congress and the presidency were under unified Republican Party control.
