Donald Trump warned Democrats on Thursday that impeaching him would destroy their party, two days after voters handed them control of both chambers of Congress in the 2026 midterm elections. Asked by Sky News whether he feared a third impeachment, the president replied, "not even a little bit". The Trump impeachment warning came as Washington prepares for divided government, with the president promising to block the incoming majority with his veto while Democrats prepare investigations into his administration.

The Associated Press called the Senate for Democrats at 11:36 p.m. ET on Tuesday, once Iowa delivered the seat that put the party past a majority. The House followed at 1:24 a.m. ET on Wednesday, according to the Associated Press. Democrats flipped seven Republican-held Senate seats, in North Carolina, South Carolina, Ohio, Texas, Kansas, Iowa and Maine. NBC News projects the party will finish with at least 258 seats in the House, well above the 218 needed for a majority. Alaska and Mississippi remained uncalled on Thursday, so the final margins could still grow. The new Congress convenes on 3 January, when House Democratic leader Hakeem Jeffries is positioned to become the first Black speaker of the House.

Trump congratulated Democrats in a Fox News interview on Wednesday, saying they "did a good job" and that he did not view the result as a blow to his presidency. He also said he would accept the results, a notable shift from a president who spent a decade claiming fraud in American elections and tried to overturn his 2020 defeat. In the same round of interviews, he blamed Republican candidates for the losses and said he would use his veto to force Democrats to negotiate. Writing online, he argued that the outcome would have been different had he been on the ballot himself, and he posted a picture of a red cap bearing the words "Mr. Veto".

Vice-President JD Vance offered a different explanation for the defeat. In a lengthy post on X, he blamed the war for the defeat. Trump agreed with that assessment in an interview, saying the war in Iran had driven petrol prices up in the short term, while insisting that barring Iran from a nuclear weapon left him no alternative. "You can't let Iran have a nuclear weapon," he said. Trump acknowledged to the Wall Street Journal that the war had played a part in voter dissatisfaction, according to NPR.

Why voters turned against the Republicans

The campaign was dominated by the cost of living. Markets reacted sharply to the result, with AI stocks giving up their post-midterm gains in a single session. An AP voter poll found that about 70% of voters wanted Congress to provide stronger checks on the president. A post-election report from Data for Progress put Trump's approval at 37%, with nearly three quarters of voters saying the cost of living had worsened since the last presidential election. Among swing voters, 41% named the economy, jobs and the cost of living as the issue that mattered most when choosing a candidate. The report found the country had shifted toward Democrats by about 15 points nationally compared with the previous presidential vote, with the largest swings among Hispanic voters and younger voters.

Both chambers changed hands in the same midterm for only the fifth time since the Second World War, according to historical reviews cited by TIME. Democrats won seats in states Trump had carried by wide margins at the last election, and Republican redistricting efforts in several states failed to deliver the advantage party leaders had expected. In Texas, Democrat James Talarico defeated Attorney General Ken Paxton by 59% to 39%, while Gina Hinojosa won the governorship, a breakthrough for Democrats in the state. Michigan elected Abdul El-Sayed, the first Muslim member of the United States Senate.

What changes when the new Congress meets

Democratic control brings subpoena power and the ability to open investigations into the Trump administration, a prospect party leaders have discussed openly since election night. A Democratic-led Senate can also slow or block nominations to cabinet posts and lifetime federal judgeships. Trump warned that any impeachment effort "would destroy the Democrat Party". A White House memo issued after the results said attempts to impeach the president would "meet the same fate as the Radical Left's previous attempts: failure", adding: "President Trump will never stop fighting."

For now, the current Republican-controlled Congress remains in place until the new term begins. Investors also repriced the outcome, with Bitcoin erasing its post-election rally within a day. Trump told Fox News he would veto Democratic legislation and expected the new majority to seek a deal within months, saying the party would come to the negotiating table once vetoes had stalled its agenda. Democrats, meanwhile, have signalled that oversight hearings will be an early priority. Congress returns on 9 November, when the new balance of power will start to shape the budget, nominations and the investigations both parties are preparing.
