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

With a dozen races still to be called, the G.O.P. was two seats away from the 218 that would allow the party to claim a coveted governing trifecta: control of the House, Senate and White House.

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.
