“In the House, as I did in my private law practice, I have fought every day for the Constitutional rights of every individual citizen and to protect the sovereignty of this nation,” Hageman said in a statement. “As I announce my candidacy to continue to represent Wyoming, now as a United States Senator, I humbly ask the voters for their support.”

Hageman first arrived on the national political scene in 2022, when she successfully won a primary against then-incumbent Rep. Liz Cheney. Cheney was one of 10 House Republicans who voted to impeach President Donald Trump during his first term, and one of a handful who either lost a primary to a Trump ally or chose to retire in the aftermath.

The congresswoman said she is a “strong supporter of Trump” and wants to advance his “America First” agenda in the Senate, as well as continue to prioritize the needs of the Western states. She is a water and property rights attorney and constitutional advocate of regulatory reform.

Club For Growth PAC endorsed Hageman’s candidacy almost immediately in a statement on Tuesday.

“Since being elected to Congress, Rep. Harriet Hageman has consistently supported free-market policies, opposed spending increases, and championed deregulatory efforts that have allowed small businesses to thrive,” Club for Growth PAC President David McIntosh said. “We are proud to endorse Hageman for Senate, and we look forward to ensuring she continues to lead by example on Capitol Hill.”

Hageman joins several fellow House colleagues on both sides of the aisle who are opting not to seek reelection to the House and are eyeing a seat in the Senate or higher office. Most Republicans who are leaving their House seats are doing so in safe red districts, meaning the conference will not need to spend considerable resources to try to hang on to the seat.

Reps. Wesley Hunt (R-TX), Ashley Hinson (R-IA), Barry Moore (R-AL), Andy Barr (R-KY), Buddy Carter (R-GA), and Mike Collins (R-GA) are also seeking a Senate seat in 2026 in their home states.

Of the seven GOP lawmakers, most face contested primaries, with Hunt challenging incumbent Sen. John Cornyn (R-TX) and Attorney General Ken Paxton. Hinson, meanwhile, is the front-runner to replace retiring Sen. Joni Ernst (R-IA).
