Wyoming’s lone congressional Rep. Harriet Hageman (R-WY) will run for outgoing U.S. Sen. Cynthia Lummis’ seat, according to a campaign video posted on Dec. 22. Lummis announced last week that she would not run for a second term in the U.S. Senate.
In the video, Hageman referenced working with Pres. Donald Trump to deliver “the largest tax cut in American history,” fight against “reckless RMPs [resource management plans]” and pass billions for “border security.”
Hageman primaried former U.S. Rep. Liz Cheney in 2022 after receiving an endorsement from Trump, winning 66.3% of the vote to Cheney’s 28.9%. Cheney had co-chaired a committee investigating the Jan. 6 riot at the U.S. Capitol.
In December 2024, Democratic senators blocked a bill sponsored by Hageman that would’ve transferred the defunct Pilot Butte Power Plant, which is located on the Wind River Reservation but is owned by the U.S. Bureau of Reclamation, to a local non-tribal irrigation entity.
Senate Democrats from Minnesota and New Mexico said they had issues with the Wyoming federal delegation’s “lack of consultation” with the Eastern Shoshone and Northern Arapaho tribes during the writing of their mirror House and Senate bills. Sen. John Barrasso (R-WY) denied that assertion on the floor of the upper chamber.
Both tribes have said they were not consulted by Wyoming’s leaders about the bill.
Hageman’s announcement for U.S. Senate comes as an unusually high number of lawmakers in Congress are running for governor, Senate and other local political offices.
Before heading to the U.S. House, Hageman worked as a trial attorney and graduated from the University of Wyoming (UW).
Her decision to run for the Senate means the race for Wyoming’s only seat in the House will be wide open in the upcoming 2026 election.
