MyKayla Skinner has doubled down on her remarks about Biles as the Olympic gymnast and former swimmer trade barbs on social media.

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.

Former Olympic silver medalist gymnast Mykayla Skinner threw her opinion into the ring in the ongoing Simone Biles-Riley Gaines feud recently, calling Biles's social media posts "deeply troubling". And it is just the latest chapter in a long-running feud between the two former teammates that exploded during last summer's Olympics.
