Wyoming’s Hageman Jumps Into Senate Race — With Trump’s Stamp of Approval

NBC News, ABC News, CNN, and the Hill contributed to this report.

Wyoming Rep. Harriet Hageman is officially running for the US Senate, aiming to take over the seat being left open by retiring Republican Sen. Cynthia Lummis.

Hageman launched her campaign Tuesday with a video that didn’t exactly bury the lede: she’s pitching herself as a full-speed-ahead supporter of President Donald Trump’s agenda — and she made sure voters knew it.

“I stood with President Trump,” Hageman says in the three-minute spot, ticking through familiar highlights: the tax cut, border enforcement, and deportation funding.

Her message is basically: I’ve been in the fight, I know the playbook, and I’m not here for a warm-up lap.

“We must keep up this fight,” she says, framing her run as part of a bigger mission to lock in what she calls the “next great American century.”

Trump didn’t wait around to respond. Within hours, he handed Hageman what he called his “Complete and Total Endorsement” on Truth Social, calling her a “TOTAL WINNER” and promising she’ll “ALWAYS” deliver for Wyoming.

Hageman, 63, has been Wyoming’s lone member of the US House since 2023. She rose to national attention in 2022 when she knocked off then-Rep. Liz Cheney in the GOP primary — a race where Trump’s endorsement was basically a megaphone. Cheney was one of Trump’s loudest Republican critics, and Wyoming Republicans made it clear which direction they wanted their party to go.

Now Hageman is trying to move up a rung — and she’s doing it in a state where winning the Republican primary is often the whole ballgame. Trump carried Wyoming by nearly 46 points last year, and Hageman won reelection in 2024 by about 48.

Still, the job comes with some heat. Earlier this year, Hageman faced a rough town hall where she got booed while talking about federal spending cuts, the Department of Government Efficiency and Social Security. She brushed it off as “over the top,” and an adviser waved it away as “political theater.”

As for why Senate — and why now — Hageman suggested she doesn’t think Wyoming can afford a rookie learning curve. She told Cowboy State Daily she had considered running for governor but decided the Senate race mattered more because the next senator needs to “hit the ground running” the moment Lummis is gone.

The bigger question is whether anyone serious tries to challenge her in the primary, especially with Trump already in her corner. But with a governor’s race opening up and Hageman’s House seat soon to be vacant, Wyoming Republicans are about to have plenty of reasons to reshuffle the deck.
