With all eyes on the Beehive State’s newly drawn 1st Congressional District, another fight is brewing in northern Utah, where U.S. Rep. Blake Moore has drawn a challenger from a state lawmaker.

House Rep. Karianne Lisonbee, R-Clearfield, officially announced her candidacy Tuesday in the 2nd Congressional District, setting up a primary fight between Utah’s only member of Congressional leadership and a prominent member of the Legislature.

“Northern Utah deserves a representative who fights for our conservative values,” Lisonbee wrote in a post on the social media platform X on Tuesday morning.

Lisonbee’s campaign website lists her “A+ Lifetime NRA rating” and “100% pro-life voting record” prominently, as well as her former title as majority whip in the Utah House of Representatives.

Lisonbee was first elected to the Legislature in 2016. She has run a number of prominent bills related to firearms, criminal justice and abortion, and made national headlines in 2022 when she said she trusted women to “control their intake of semen.”

Moore was elected to Congress in 2020, and he has served in House leadership as the vice chair of the House Republican Conference since 2023. He has faced a Republican primary challenge in each of his previous campaigns.

Moore currently sits on the House Ways and Means Committee and House Committee on the Budget. He was instrumental in the crafting and passage of last year’s One Big Beautiful Bill, and pushed for an expansion of the Child Tax Credit that was ultimately included in the massive spending package.

Moore has been largely supportive of President Donald Trump, but he has been an outspoken critic of the president’s mass tariff scheme and recently called for an investigation into the killing of Alex Pretti by federal agents in Minneapolis.

“Blake welcomes the opportunity to share his conservative record and earn the votes of constituents,” a campaign spokesperson said in a statement to The Salt Lake Tribune following Lisonbee’s announcement. “As a drafter of the working families tax cuts, Blake is working hard to maintain our majority and help Utahns succeed.”

Trump endorsed Moore on his Truth Social account in November, writing that the congressman was a “Tremendous Champion for Utah’s 1st Congressional District!”

“Blake has President Trump’s endorsement and has been working hard with Speaker Johnson to support working families, make our country safe, secure the border, establish Trump Accounts for the next generation, and focus on affordability and cost of living,” the spokesperson said.

Lisonbee’s campaign did not immediately respond to a request for comment Tuesday afternoon.
