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 first presidency.

Congressional Record

Volume 163 (2017)

Volume 164 (2018)

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.

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.^[2][3][4][5]
