Republicans will keep their majority in the U.S. House of Representatives, the Associated Press projected Wednesday.

Republicans have won enough seats to control the House of Representatives, completing the party’s sweep into power and securing their hold on both chambers of Congress and the White House. Republicans gained control of the Senate last week.

In yet another blow to Democrats, Donald Trump will begin his presidency with a trifecta of Republican control in Washington.

WASHINGTON—Republicans clinched control of the House more than a week after Election Day, with GOP lawmakers on course for another narrow majority that will test party unity as they work to pass President-elect Donald Trump’s second-term agenda.

Republicans have officially won a full trifecta of power in Washington, D.C., following GOP victories in several key U.S. House contests.

The party protected vulnerable incumbents and picked off Democrats in competitive districts, handing the president-elect a unified Congress to enact his agenda.

President-elect Trump now has a clear path to enact his agenda and fill out his administration with both the House and Senate in Republican hands come January.

Republicans have managed to hold onto their slim majority in the House of Representatives, NBC News projects.

The majority will give President-elect Donald Trump a chance to enact his preferred policy agenda, but the slim margins in both chambers could still provide for some stumbling blocks.

U.S. President-elect Donald Trump's Republicans on Tuesday inched closer to winning a majority in the House of Representatives and with it full control of Congress, which would give Trump power to advance his agenda when he returns to the White House in January.
