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

Recent race calls by The Associated Press guarantee Republicans a narrow majority in the House and a three-seat majority in the Senate.

The campaign for control of the House was waged on a narrow playing field of roughly three dozen competitive districts. While the presidential campaign was centered in seven purple states in the Midwest and the Sun Belt, the contest for the House featured a cluster of critical swing races in the blue states of New York and California.
