United States President Donald Trump posted a strong endorsement of Senator Steve Daines on Truth Social, calling him a "great man" and a "tremendous senator" for Montana. He credited Daines, chair of the National Republican Senatorial Committee, with helping elect "America First Patriots" and praised his stance on the economy, border security and energy policy. "He will not let you down," Trump wrote.
Trump also addressed Arizona politics, saying he previously endorsed Karrin Taylor Robson when she was the only candidate running. After Rep. Andy Biggs entered the race, Trump said both were "fantastic candidates" and gave them his "complete and total endorsement."
