President Donald Trump put Maine’s Democratic Governor Janet Mills on notice Friday, calling her out to her face over her refusal to comply with a federal order barring biological males from competing in women’s sports.

During a White House meeting with governors, Trump directly confronted Mills about her opposition to his executive order, making it clear that failure to comply would come at a price—specifically, the loss of federal funding.

“The NCAA has complied immediately, by the way. That’s good,” Trump said during the exchange, before singling out Mills. “Is Maine here? The governor of Maine? Are you not going to comply with it?” he asked.

Mills, who has been vocal in her support of allowing biological males to compete against women, refused to back down. “I’ll comply with state and federal laws,” Mills said.

But Trump wasted no time in shutting her down. “Well, we are the federal law,” he reminded her. “You better do it,” Trump warned.

“You better do it because you’re not going to get any federal funding at all if you don’t. And by the way, your population, even though it’s somewhat liberal, although I did very well there, your population doesn’t want men playing in women’s sports.”

Trump then made it crystal clear that he’s prepared for any legal challenges from the Maine governor. “So you better comply because otherwise, you’re not getting any federal funding,” he said.

“We’ll see you in court!” Mills said.

The president added, “I look forward to that. That should be a real easy one. That should be a real easy one. And enjoy your life after governor because I don’t think you’ll be in elected politics.”

WATCH:

Trump’s firm stance comes amid a growing national backlash against efforts to allow transgender athletes to compete in female sports—an issue that has sparked heated debates across the country. Mills, however, appears to be digging in her heels, setting up a potential legal showdown with the Trump administration.

Mills has consistently shown strong support for transgenderism. In May 2019, she signed legislation banning conversion therapy for minors, a practice widely discredited by major medical associations.

In February, President Trump signed an executive order prohibiting transgender women and girls from participating in female sports. This aligned with his administration’s policy that defines gender strictly based on biological sex at birth.

The order was expected to have significant implications for federally funded institutions and athletic programs, potentially conditioning federal funding on adherence to a biological sex-based definition of sports participation.

Following President Trump’s executive order, the NCAA announced a policy change prohibiting transgender athletes born male from competing in women’s sports. The decision aligned with the administration’s directive to enforce sex-based distinctions in athletics, aiming to provide a uniform standard across all states.

The policy was effective immediately and applied across all NCAA divisions. The executive order also mandated that federal agencies and state attorneys general enforce this prohibition, with potential consequences for educational institutions that fail to comply, including the revocation of federal funding.
