Former MSNBC host Keith Olbermann called on former NCAA swimmer Riley Gaines to acknowledge that she was a terrible athlete in a post that is receiving backlash on social media.

“Can you just address the reality and move past it?” Olbermann wrote on X, formerly known as Twitter. “You sucked at swimming. That’s why you lost.”

Gaines famously tied with transgender swimmer Lia Thomas, a biological male and former member of the University of Pennsylvania women’s swim team.
