Olympian Simone Biles faces fierce backlash after clash with Riley Gaines over trans athletes debate

Women's sports advocate and 'OutKick' host Riley Gaines joins 'Fox & Friends Weekend' to weigh in on a biological man winning a women's California track and field championship. 

Seven-time Olympic gold medalist Simone Biles received harsh backlash on social media after the gymnastics star sparred with former 12-time NCAA All-American swimmer Riley Gaines over the debate surrounding transgender athletes competing in girls’ and women’s sports. 

Gaines, a former University of Kentucky swimmer and current OutKick contributor and host of the "Gaines for Girls" podcast, took to X on Friday to call out the Minnesota State High School League for posting a picture of the new state champions, Champlin Park High School.

The school has made headlines because its dominant performance on the way to the title game was led by junior pitcher Marissa Rothenberger, a transgender athlete competing on the team.

In response to Gaines’ criticism of the post, Biles posted a message calling Gaines "truly sick" over her stance on trans athletes. She even launched a personal attack at Gaines. 

"You’re truly sick, all of this campaigning because you lost a race. Straight up sore loser," Biles said, referencing Gaines competing against former UPenn swimmer Lia Thomas at the 2022 NCAA championships.
