Republican Rep. Harriet Hageman is running to replace retiring Sen. Cynthia Lummis in Wyoming.
In her announcement video, Ms. Hageman presented herself as a pro-energy champion who leans on her faith and community and who has fought to help President Trump pass tax cuts and secure the southern border.
“We must keep up this fight, and that is why today I am announcing my campaign for United States Senate,” Ms. Hageman said. “This fight is about making sure this next century sees the advancements of the last, while protecting our culture and our way of life.”
“We must dedicate ourselves to ensuring that the next 100 years is the next great American century,” she said. “Wyoming is critical for achieving that goal.”
Ms. Hageman, 63, announced her bid days after Ms. Lummis announced she would not seek re-election. The incumbent Republican said she had a “change of heart.”
“In the difficult, exhausting session weeks this fall I’ve come to accept that I do not have six more years in me,” Ms. Lummis said on Friday. “I am a devout legislator, but I feel like a sprinter in a marathon. The energy required doesn’t match up.”
The Senate seat in red Wyoming is expected to remain safely in GOP hands in 2026. Ms. Hageman is considered to have an advantage in the Senate race due to representing the entire state in Wyoming’s at-large House district.
A two-term House lawmaker, Ms. Hageman gained national attention after she defeated Rep. Liz Cheney in the 2022 GOP primary. She challenged Ms. Cheney after she emerged as the most prominent Republican critic of Mr. Trump on Capitol Hill.
Ms. Cheney broke with her party by blaming Mr. Trump for inciting the Jan. 6, 2021 attack on the U.S. Capitol. Mr. Trump backed Ms. Hageman.
Ms. Lummis, meanwhile, was the only woman founding member of the House Freedom Caucus, a conservative group of occasional rabble rousers who have pushed the party’s agenda to the right.
Last week, Ms. Hageman praised Ms. Lummis on social media for serving Wyoming “with integrity, independence and unwavering dedication” for 46 years.
“From the ranch to the halls of Congress, she built one of the most distinguished careers in our state’s history, strengthening both Wyoming and nation through her service,” Ms. Hageman said. “I’m proud to call her a lifelong friend and grateful for her extraordinary service.”
Sen. Tim Scott of South Carolina, chair of the National Republican Senatorial Committee, the Senate GOP’s campaign arm, endorsed Ms. Hageman, calling her a “battle-tested conservative, a trusted Trump ally, and the fighter that Wyoming has come to rely on.”
“With the support of President Donald J. Trump and the backing of Wyoming voters, I’m looking forward to welcoming Hageman to the U.S. Senate in 2026,” he said.
