Trump made note of that when he endorsed her in March, saying that she is “working closely with me to make America the [cryptocurrency] Capital of the World.”
The announcement makes her the fifth Senate Republican to opt against seeking reelection next year, joining Sens. Joni Ernst (Iowa), Mitch McConnell (Ky.), Thom Tillis (N.C.) and Tommy Tuberville (Ala.).
Rep. Harriet Hageman (R-Wyo.) is widely viewed as a leading potential contender in the deeply Republican state. The primary is scheduled for mid-August.
Her departure also sets the stage for another competitive Republican primary
Wyoming has not elected a Democrat to the Senate since 1977, The Hill added.
In September, Trump endorsed Rep. Ashley Hinson (R-Iowa) in her bid to succeed Ernst.
In a Fox News interview, Hinson also declared that she is “proud to stand” with the president.
Hinson, a former TV news anchor now in her third term representing Iowa’s 2nd Congressional District, highlighted her support for Trump as she launched her Senate campaign. “I’m running to be President Trump’s top ally in the United States Senate,” she said
“I know Ashley well, and she is a WINNER!” Trump noted in a social media post. “A Loving Wife and Proud Mother of two sons, Ashley is a wonderful person, has ALWAYS delivered for Iowa, and will continue doing so in the United States Senate.”
Trump’s backing comes on the heels of endorsements from Senate Majority Leader John Thune and the National Republican Senatorial Committee, the GOP’s Senate campaign arm.
“We need conservative fighters in the Senate — and that’s exactly what we’ll get with Ashley Hinson,” Thune noted on Friday, lending is endorsement as well.
He added: “Ashley Hinson will be an outstanding Senator, and has my Complete and Total Endorsement – SHE WILL NOT LET YOU DOWN!”
Tim Scott of South Carolina noted: “Having traveled Iowa with Ashley, I know she is the fighter the Hawkeye State needs to deliver President Trump’s agenda in 2026 and beyond.”
