Simone Biles and Riley Gaines traded social media barbs over the latter's recent comments advocating for the exclusion of transgender athletes in women's sports.

"You're truly sick, all of this campaigning because you lost a race. Straight up sore loser," Biles wrote on X. Biles was responding to Gaines' own X comments Friday night after the Champlin Park girls softball team led by transgender pitcher Marissa Rothenberger won the state's Class AAA championship.

Simone Biles is calling out former U.S. swimmer-turned-right-wing talking head, Riley Gaines. The legendary Olympian went to social media on Saturday to call out Gaines, who has been critical of transgender athletes.
