Gaines, a former collegiate swimmer turned right-wing activist, has clashed with Biles online while campaigning against transgender women in sports.

Olympian and former University of Utah athlete MyKayla Skinner has weighed in on the social-media spat between Simone Biles and Riley Gaines, saying that she was “belittled” and “ostracized” by Biles, her former teammate. She did not offer specifics.

Riley Gaines revealed that she is pregnant with her first baby, a girl, during an event on June 14. She included a direct dig at Simone Biles amid their feud when she announced that she and husband Louis Barker are expecting.
