Republicans have secured a majority in the US House of Representatives, extending their hold on the lower chamber and delivering a governing trifecta in Washington that could give Donald Trump sweeping power to enact his legislative agenda. The Associated Press determined on Wednesday evening that Republicans had won at least 218 seats in the 435-member House after a victory in Arizona, a call that came more than a week after polls closed across the US and as Trump made cabinet announcements that sent shockwaves through Washington. The call ensures Republicans will continue to have a large say in key matters such as government funding, debt ceiling negotiations and foreign aid, and it spells an end to Democrats’ hopes that the lower chamber could serve as a blockade against Trump’s agenda. Republicans had already won the White House and regained a majority in the Senate, so their victory in the House provides them with the last component of their governing trifecta. Although they will have a slim majority, Republicans have indicated they will use their trifecta to maximum effect when the new Congress is seated in January. “We have to deliver for the people, and we will,” the Republican House speaker, Mike Johnson, told Fox News last week. “President Trump wants to be aggressive. He wants to go big and we’re excited about that. We’re going to get to play offense.” Trump’s selection of at least three House Republicans to join his administration further complicates the math for Johnson. Trump had already tapped the New York representative Elise Stefanik to serve as ambassador to the United Nations and Mike Waltz, the Florida representative, to fill the role of national security adviser. On Wednesday, Trump announced he would also nominate Matt Gaetz, the Republican congressman of Florida, as his attorney general. A rightwing firebrand, Gaetz was a thorn in the side of former House speaker Kevin McCarthy, eventually leading the successful charge to oust McCarthy from his role. Reaction to Gaetz’s nomination ranged from puzzled to outraged, even from members of the president-elect’s own party. Despite the increasingly narrow majority, Johnson brushed off concerns about how Trump’s picks might affect House Republicans’ ability to legislate. “We have an embarrassment of riches,” Johnson said on Tuesday. “We have a really talented Republican conference. We’ve got really competent, capable people here. Many of them could serve in really important positions in the new administration, but President Trump fully understands and appreciates the math here, and it’s just a numbers game.” Democrats unsuccessfully campaigned on a need to curtail the current “dysfunction” in Congress, after Republicans’ narrow majority repeatedly brought the House to a standstill. When Republicans took control of the House in January 2023, it took 15 rounds of voting to elect Kevin McCarthy as speaker, as roughly 20 hard-right members withheld support from their conference’s nominee. Nine months later, McCarthy was ousted after eight of his Republican colleagues voted with House Democrats to remove him as speaker. After McCarthy’s departure, Johnson, then a relatively unknown Republican member from Louisiana, ascended to the speakership following a tumultuous election. Over the past year, Johnson stretched himself thin to appease members of his ideologically diverse conference. His efforts fell short for some, including Marjorie Taylor Greene, a hard-right member from Georgia. Greene attempted to oust Johnson as speaker in May, but that resolution was easily quashed by a chamber seemingly exhausted by the turmoil that defined this session of Congress. Despite those hurdles, Republicans were able to keep their hold on the House and on Wednesday, Johnson won the Republican nomination to stay in the job as speaker and is on track to keep the gavel after a full House vote in the new year. Trump gave Johnson a welcome boost during a meeting with House Republicans in Washington, when he endorsed the speaker’s bid to extend his tenure and indicated that Johnson has his full support. Johnson returned the praise by celebrating Trump as a “singular figure in American history”. “They used to call Bill Clinton the comeback kid,” Johnson said. “[Trump] is the comeback king.” Although Democrats fell short in their campaign to flip the House, they touted the party’s ability to mitigate its losses in a difficult national environment. Hakeem Jeffries, the House Democratic leader, pointed to the party’s gains in his home state of New York as evidence of their effort. “Donald Trump did better than almost any other Republican presidential candidate in modern political history here in New York state and even won several of the districts that we either held or flipped. And notwithstanding that, we were able to defeat three Republican incumbents,” Jeffries told Spectrum News’ NY1 last week. “And so, I think that there are lessons to be learned from this election in all directions, and we will certainly do an after-action analysis at the appropriate time.” That postmortem may help Democrats win back a majority in the 2026 midterm elections, but for now, they must face the reality of a fully Republican Congress ready and willing to do Trump’s bidding.
