WASHINGTON, DC - February 29, 2024: U.S. Rep. Nancy Mace

Rep. Nancy Mace (R-S.C.)'s failed efforts to censure Rep. Ilhan Omar (D-Minn.) for what Mace described as "disgraceful remarks" about the assassination of conservative podcaster Charlie Kirk has her at odds with members of her own party, Politico reports.

Mace, Politico says, is "locked in an escalating personal clash" with Rep. Cory Mills (R-Fla.). The Florida Republican joined three other GOP members of the House who joined all Democrats in voting down Mace's resolution, which fell short on Wednesday by just one vote.

Mills cited "First Amendment issues" as the reason for his vote. This prompted Mace to accuse him and other Republicans of "stifling free speech" in opposing her efforts to do just that to Rep. Omar.

Mace also claimed Mills threatened her by text, which Mills, whose ex-girlfriend claims he threatened her, too, denied in a Thursday interview with Politico.

Rep. Mills told Politico he reminded her about her comments about the January 6 insurrection, in which she said: “What would have happened if you shared the video of you condemning President Trump over J6 for free speech?”

“And so, if reminding someone of their own remarks is a threat, well, then that means everyone threatens each other every day to remind someone, ‘Hey, you voted for this, and you did this and you voted for this,’” Mills said.

On Wednesday, Mace called the GOP opposition "gross."

Mills said her outrage was more personal.

“This is typical, I’m sorry, but like, I respect Nancy, I like Nancy, I’ve always supported Nancy,” he continued. “But she’s upset that she didn’t get one thing passed because she has some back-and-forth with Ilhan that has nothing to do with me.”
