Lummis said it was a blessing to work with Sen. John Barrasso (R-Wyo.) and then-Sen. Mike Enzi (R-Wyo.), while she was still in the House, and with Barrasso and Rep. Harriet Hageman (R-Wyo.) while junior senator of Wyoming since 2021.
“Deciding not to run for reelection does represent a change of heart for me, but in the difficult, exhausting session weeks this fall, I’ve come to accept that I do not have six more years in me,” she said.
“I am a devout legislator, but I feel like a sprinter in a marathon. The energy required doesn’t match up.”
Lummis added that she was honored to have the support of President Donald Trump and the “opportunity to work side by side with him to fight for the people of Wyoming.”
She said that the next year will involve her “continuing this partnership” as she puts her energy into bringing important legislation to the president’s desk in 2026 and working to retain the GOP’s majority in the Senate.
“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 [the] nation through her service,” she said.
“I’m proud to call her a lifelong friend and grateful for her extraordinary service.”
Lummis, who has only served one term in the Senate, is the fifth Republican senator who has announced intentions not to seek reelection in 2026.
When Lummis was sworn into the Senate in January 2021, she became the first woman to serve as a senator from Wyoming.
She previously served in the House from 2009 to 2017, representing Wyoming’s at-large congressional district.
Before her terms in Congress, Lummis also served as Wyoming State treasurer for eight years and as a member of the Wyoming Legislature—both in the state House and Senate—for 14 years.
