Reality TV star, former Olympic and California gubernatorial hopeful Caitlyn Jenner has weighed in on her first political hot button issue -- whether or not trans gender athletes should play according to their biological identity or their chosen gender.

Jenner, a trans woman, told TMZ that she believes that if you’re born a biological boy, and you’re a trans girl, you should not be allowed to compete in girls’ sports while in school, adding it was  “a question of fairness.”

Jenner, a 1976 decathlon Olympic gold medalist came out as a transgender woman in 2015.

“That's why I oppose biological boys who are trans competing in girls' sports in school. It just isn't fair. And we have to protect girls’ sports in our schools,” Jenner said Saturday during a brief interview in a Malibu parking lot.

It was Jenner's first comment on the controversial issue since announcing her candidacy to replace Gov. Gavin Newsom in a recall election. Five states have passed laws or implemented executive orders this year limiting the ability of transgender youths to play sports or receive certain medical treatment. There’s been a vehement outcry from supporters of transgender rights.

Jenner, a Republican, supported Donald Trump in the 2016 presidential election but later criticized his administration for some discriminatory actions against transgender people.
