Senate Majority Leader John Thune said Tuesday he will continue supporting Sen. John Cornyn despite President Donald Trump endorsing Texas Attorney General Ken Paxton in one of the most closely watched Republican Senate primaries of the 2026 cycle.
Speaking to reporters following Trump’s endorsement announcement, Thune praised Cornyn as “a principled conservative” and an “effective senator” for Texas, signaling a rare split between Senate Republican leadership and the president.
“Cornyn is a principled conservative. He is a very effective senator for the state of Texas,” Thune said.
“None of us can control what the president does. That doesn’t change the way I feel. I will continue to be supportive of Senator Cornyn in his re-election,” Thune added.
