Rep. Dan Newhouse (R-WA) announced on Wednesday that he will not seek re-election in the 2026 midterms. “I am announcing today that I will not seek reelection to the U.S. House of Representatives. Serving the Fourth District of Washington has been the honor of my life, and this decision comes with no reservations or remorse, only gratitude for the tremendous opportunity to have represented my home state in Congress,” Newhouse said in a statement posted to X. Today I am announcing I will not seek reelection in 2026. See my statement below: pic.twitter.com/374ez1r0Lc — Rep. Dan Newhouse (@RepNewhouse) December 17, 2025 Newhouse was one of 10 House Republicans who voted to impeach President Trump after January 6, 2021. He is among the final Republicans in the lower chamber who voted for Trump’s impeachment. BREAKING: RINO Dan Newhouse is retiring from Congress, leaving only 1 of the 10 Republicans who voted to impeach Trump left in the House. https://t.co/4pq4AzQKqm pic.twitter.com/FWQfBKekhQ — johnny maga (@_johnnymaga) December 17, 2025 POLITICO has more: Newhouse represents a safe red seat, and he narrowly defeated a Trump-backed GOP challenger in 2024. His departure from Capitol Hill could leave Rep. David Valadao (R-Calif.) as the only remaining House Republican who voted to impeach Trump serving after November’s election. But Valadao faces a tough reelection in a battleground district. And on the Senate side, where many who voted to convict Trump have already left or announced plans to retire, GOP Sens. Bill Cassidy (La.) and Susan Collins (Maine) are facing competitive races this cycle. Should they lose, it could leave Sen. Lisa Murkowski (R-Alaska) as the only GOP senator who voted against Trump remaining. Not including Newhouse, 42 House members — 23 Republicans and 19 Democrats — have decided they won’t run for reelection next year, according to Ballotpedia’s tracker. With Newhouse announcing his retirement, MAGA has a golden opportunity to win the safe red seat. Breaking Dan Newhouse will NOT be seeking reelection. Dan is one of the few Republicans in the House left who did vote to impeach Trump. He represents a R+20 district, and in 2024 won reelection by 6 points, due to the jungle primary system in WA. Big opening for MAGA! pic.twitter.com/ScbWRm6593 — America First Insight (@AF_Insight) December 17, 2025 NBC News shared further: Newhouse won re-election by 6 percentage points last year, beating Trump-backed Jerrod Sessler in the general election after Sessler beat him in the GOP primary. Washington uses a top-two primary system, meaning the top two vote-getters in a primary move onto the general election, regardless of party. Sessler, a businessman and former NASCAR driver, is running in the district again in 2026, which will hold its primary in August. Sessler, who is also a Navy veteran, has said that he was in Washington on Jan. 6, 2021, and attended Trump’s speech. He said that he did not enter the Capitol that day. Sessler has defended Jan. 6 rioters, including those who were prosecuted — and pardoned by the president earlier this year — for their actions at the Capitol that day. He’s called them “innocent Americans” and has spread debunked conspiracy theories about the 2020 presidential election.
