President Donald Trump threatened to withhold federal funding from California on Tuesday after a transgender athlete competed in the female track and field state qualifiers.

Trump said he would speak to Gov. Gavin Newsom (D-CA) on Tuesday and mentioned that the California governor recently said allowing biological males to compete in female sports was “unfair.”

In a Truth Social post, Trump said it was “totally demeaning to women and girls” that officials allowed the 16-year-old transgender athlete to compete in the state track event.

“California, under the leadership of Radical Left Democrat Gavin Newscum, continues to ILLEGALLY allow ‘MEN TO PLAY IN WOMEN’S SPORTS,” Trump posted. “This week a transitioned Male athlete, at a major event, won ‘everything,’ and is now qualified to compete in the ‘State Finals’ next weekend. As a Male, he was a less than average competitor. As a Female, this transitioned person is practically unbeatable.”

Criticism over the transgender athlete competing in the female event came after Newsom called it “deeply unfair” to allow biological males to compete in female sports on his podcast in March.

“The Governor, himself, said it is ‘UNFAIR,’” Trump posted. 

Trump signed an executive order in February prohibiting biological males from competing in female sports. His administration has been enforcing Title IX civil rights protections on the basis of biological sex, as opposed to gender identity. The government is interpreting policies that require females to compete against transgender athletes, instead of having female-exclusive sports, as Title IX violations.

The Trump administration has been in a legal battle with Maine over its allowance of biological males to compete in female sports. 

The government has withheld funding from Maine and frozen millions of dollars in funding from the University of Pennsylvania due to similar practices.
