Gaetz feuded with a top Thune and Trump ally, Sen. Markwayne Mullin (R-Oklahoma), earlier this year. “@MattGaetz is a liar,” Mullin wrote in a post on X. “Those of us who have worked with him already know that. He should focus on his own ethics issues instead of spreading false Hill rumors.”

But on CNN on Wednesday, Mullin said he “completely” trusts Trump’s decision. He added Gaetz would need to “sell himself” on Capitol Hill to get confirmed.
