The U.S. Department of Justice filed suit Wednesday, two days after the California Department of Education said it would not strip trans athletes of their medals or repeal a 2013 law that allows student-athletes to compete on sports teams and use facilities that reflect their gender identity.

The Trump administration signaled that it would pursue enforcement actions against the state and previously threatened to cut federal education funds.

The US government sued California for allowing transgender students to participate in female sports, escalating a broad legal showdown between President Donald Trump’s administration and the Democratic-led state.
