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.

MyKayla Skinner has entered the chat. The retired Olympic gymnast, 28, has accused former teammate Simone Biles of bullying, days after the 11-time Olympic medalist apologized to Riley Gaines for comments made during a heated social media debate over transgender athletes.

MyKayla Skinner called out Simone Biles for years of bullying, which resurfaced after Biles' recent remarks on swimmer Riley Gaines.
