Trump-Backed Hageman Wins Wyoming GOP Senate Primary

Rep. Harriet Hageman has won the Republican primary for Wyoming's open Senate seat, NBC News projects, advancing to the general election in the deep-red state.

Hageman had the backing of President Donald Trump as she ran against four Republican opponents. Trump offered his "complete and total endorsement" on Truth Social shortly after she announced her candidacy in December.

"I know Harriet well, and she is a TOTAL WINNER!" Trump wrote. "Harriet has ALWAYS delivered for Wyoming, and will continue to do so in the United States Senate."

Hageman won her House seat with Trump's support in 2022, when she ousted Rep. Liz Cheney, a Trump critic, in a Republican primary. Trump backed Hageman after Cheney voted to impeach him in 2021 and later joined the House committee investigating the January 6 Capitol riot.

Hageman emerged from a primary field that included former Kirby Mayor Sam Mead, who partially self-funded his campaign. His uncle, Matt Mead, was governor from 2011 to 2019. Cheney conceded her 2022 primary at an event at the Mead family ranch, according to Wyoming Public Media, and Sam Mead said he was "proud of her for standing up for the truth."

The Wyoming Senate seat is open this year after Sen. Cynthia Lummis, a Republican, announced in December that she would not seek re-election. Lummis, 71, said at the time that she did "not have six more years in me."

Wyoming is a deep-red state and has not had a Democratic senator since 1962. Trump won more than 71% of the vote there in 2024, and Hageman was easily re-elected to her House seat that year with 71% of the vote.

Hageman, a lawyer before entering Congress, serves as Wyoming's lone House member on the Judiciary and Natural Resources committees. Wyoming was the least populated state as of the 2020 census, with just under 577,000 residents.
