Harriet Hageman

Hageman was born in Douglas, Wyoming, in 1962 and grew up on a ranch near Fort Laramie, Wyoming.⁠[1][2]

She attended Casper College on a livestock judging scholarship and was a member of its livestock judging team, leaving the college in 1983. In 2010 the Casper College Foundation named her one of that year’s Distinguished Alumni.⁠[3][2]

She earned a bachelor’s degree in business administration from the University of Wyoming in 1986 and a law degree from the University of Wyoming College of Law in 1989.⁠[1][2]

After law school Hageman clerked for Judge James E. Barrett of the U.S. Court of Appeals for the Tenth Circuit, and then practiced law in Michigan and Denver.⁠[2][4]

In 1997 she returned to Wyoming to join the Water and Natural Resources Division of the Wyoming Attorney General’s Office, where she worked on the water-rights case Nebraska v. Wyoming. In August 2000 she opened her own law firm, and she later co-founded Hageman and Brighton, P.C., with attorney Kara Brighton.⁠[2][4]

Her practice covered water and energy law, water and property rights, and federal land and wildlife management; she tried cases against federal agencies and is admitted to practice before the U.S. Supreme Court. On gray wolf management she represented a group known as the “Wolf Coalition.”⁠[3][2]

She also served as an adjunct professor of law at Central Michigan University, sat on the steering committee of the Wyoming Business Alliance, the advisory committee of the Rocky Mountain Land Use Institute and the board of litigation of the Mountain States Legal Foundation, and co-created the Wyoming Conservation Alliance with Kara Brighton. In 2011 she was inducted into the Wyoming Agriculture Hall of Fame.⁠[2][4]

In 2018 Hageman ran in the Republican primary for governor of Wyoming and finished third with 25,052 votes (21.5%); Mark Gordon won with 33.4%, and Foster Friess received 25.6%.⁠[1][4]

In May 2019 Hageman joined the New Civil Liberties Alliance as senior litigation counsel.⁠[4]

After receiving Donald Trump’s endorsement, Hageman defeated incumbent Representative Liz Cheney in the August 16, 2022, Republican primary for Wyoming’s at-large U.S. House seat, 66.3% to 28.9%.⁠[1][5]

In the November 8, 2022, general election she defeated Democrat Lynnette Grey Bull, 68.2% to 24.4%.⁠[1]

In the 118th Congress Hageman served on the House Judiciary Committee, including its subcommittees on the Administrative State, Regulatory Reform, and Antitrust and on the Constitution and Limited Government and the Select Subcommittee on the Weaponization of the Federal Government, and she chaired the Natural Resources Committee’s Subcommittee on Indian and Insular Affairs.⁠[1]

In December 2024 Democratic senators blocked a bill she sponsored that would have transferred the defunct Pilot Butte Power Plant, which sits on the Wind River Reservation and is owned by the U.S. Bureau of Reclamation, to a local non-tribal irrigation entity.⁠[5]

She won reelection in the November 5, 2024, general election with 184,680 votes (70.6%) over Democrat Kyle Cameron, and took the oath of office for the 119th Congress on January 3, 2025.⁠[1][6]

In the 119th Congress she chairs the Natural Resources Committee’s Subcommittee on Water, Wildlife and Fisheries and serves on its Subcommittee on Energy and Mineral Resources, sits on the Judiciary Committee’s subcommittees on the Administrative State, Regulatory Reform, and Antitrust and on the Constitution and Limited Government, and co-chairs the Congressional Coal Caucus. She is also a member of the Select Subcommittee to Investigate the Remaining Questions Surrounding January 6, 2021.⁠[3][6]

Hageman has said her legislative priorities include reducing regulatory burdens, ending what she describes as the “weaponization” of the federal government, and ending what she calls a de facto moratorium on American energy production. In the House she pushed for stronger trucking rules, including English-language proficiency requirements for drivers, and voted for the One Big Beautiful Bill Act.⁠[3][7]

In December 2025 Republican U.S. Senator Cynthia Lummis announced that she would not seek a second term. Days later, on December 22, Hageman released a campaign video announcing her candidacy for the seat.⁠[5]

In the video she cited working with President Trump to deliver “the largest tax cut in American history,” and said she would fight what she called “reckless” resource management plans and pass billions of dollars for “border security.”⁠[5]

Hageman won the August 18, 2026, Republican primary for Wyoming’s U.S. Senate seat with 24,913 votes (62.2%); Sam Mead finished second with 31.1%, and Jimmy Skovgard, Jill Edwards and John Holtz each received single-digit shares. The Associated Press called the race before 9 p.m. that night.⁠[1][8]

After her primary win she said, “I will be proud to serve as a vigilant lookout and champion for Wyoming in the Senate.”⁠[7]

On the same day former state representative James Byrd won the Democratic nomination with 78% of the vote, becoming her general-election opponent.⁠[8]

On the night of November 3, 2026, the Associated Press declared at 9:00 p.m. EST that Hageman had won Wyoming’s U.S. Senate election, defeating Democrat James Byrd.⁠[9][1]
