A Justice Department letter threatened action over California’s policy allowing trans athletes in girls’ sports. President Donald Trump promised “large scale fines.”

Trump said “large-scale fines” would be imposed on California after AB Hernandez, a transgender athlete, claimed medals in state track-and-field championships.

The US Department of Justice is pressuring California’s public high school sports authority to abandon a policy allowing transgender girls to compete on women’s teams, following a transgender athlete’s first-place wins at the state track and field championships.
