Rep. John Curtis (R-UT) has won a four-way GOP primary to replace outgoing Sen. Mitt Romney (R-UT), dealing a blow to former President Donald Trump’s endorsement record after he supported an opponent in the race.

Curtis, who currently represents the 3rd Congressional District, received 51.6% of the vote with 50% of ballots counted when the primary was called at 10:23 pm ET, according to the Associated Press. Meanwhile, Mayor Trent Staggs, whom Trump endorsed shortly before the Utah GOP convention in April, received 28.1% of the vote. Utah House Speaker Brad Wilson and businessman Jason Walton received 14.1% and 6.2%, respectively.
