Trump threatened to fine California after a trans athlete shared the podium at a track meet Saturday under a state rule that allows trans athletes to compete as long as they don’t bump cisgender girls from the medals.

The president posted Monday on social media that Gov. Gavin Newsom “fully understands, large scale fines will be imposed” following AB Hernandez’s participation in three events.

Olympians Marion Jones and Tara Davis-Woodhall previously set state championship records in the long jump in 1993 and 2017, respectively, both surpassing 22 feet (6.7 meters). This year’s winner, Loren Webster, topped 21 feet (6.40 meters), with Hernandez trailing by a few inches.
