Republican Rep. Juan Ciscomani has won reelection to a U.S. House seat in southeastern Arizona. With his win, Republicans have enough seats to control the U.S. House.

Two vulnerable Republicans held onto their seats as a "red wave" election boosted the GOP up and down the ballot.

Boosted in part by two pivotal Arizona races, Republicans have won a majority in the U.S. House of Representatives, helping to cement total GOP control over the federal government’s elected bodies.
