The next move is up to the Trump administration after California rejects demand to bar trans-athletes from women's and girls' sports. State funding is threatened.

The decision by California officials to defy a Trump administration order to ban trans athletes from competing on teams matching their gender identity likely sets the state up for a legal showdown.

U.S. Education Secretary Linda McMahon gave California 10 days from June 27 to rescind any sports prizes awarded to trans athletes and ban them after the agency's Office of Civil Rights said that the state had violated federal anti-discrimination law by allowing transgender girls to compete with cisgender girls.
