The Trump administration is going after California following a 16-year-old trans athlete’s victories in a state track and field championship over the weekend.

The 16-year-old, AB Hernandez, a junior at Jurupa Valley High School in Riverside County, has made headlines and been at the center of protests in recent months simply for competing.

Despite protests on Saturday, Hernandez won first place in the girls’ high jump and triple jump at the State Track and Field Championships at Buchanan High School in Clovis, California. Hernandez also finished second in the long jump.

But because of a new rule instituted by the California Interscholastic Federation, multiple other student athletes also received medals in the categories that Hernandez competed in. As such, Jillene Wetteland and Lelani Laruelle also won first place in the high jump, and Kira Gant Hatcher also won first in the triple jump. Brooke White also placed second in the long jump.

“A Biological Male competed in California Girls State Finals, WINNING BIG, despite the fact that they were warned by me not to do so. As Governor Gavin Newscum fully understands, large scale fines will be imposed!!!” the president wrote on Truth Social on Monday.
