Former MSNBC and ESPN host Keith Olbermann got into a war of words with Riley Gaines Thursday, saying the two-time All-SEC first-teamer "sucked at swimming."

Cooler heads prevailed, but Olbermann took one last jab at the former college swimmer when the New York Post shared the story of their social media spat.

In the final barb, Olbermann called Gaines a "homophobe" for her fight to keep transgender women out of female sports.

Gaines hosts the "Gaines for Girls" podcast on OutKick, highlighting the issue.

"Second team all-conference. Happily for nasty, stupid, unsuccessful transphobe @Riley_Gaines she has no reputation to ruin," he posted on X, the social media platform formerly known as Twitter.

Gaines was a second-team swimmer in 2019 and 2020 before earning first-team honors her final two years at the University of Kentucky.

Gaines' collegiate resume speaks for itself, but she felt the need to remind Olbermann of her swimming accomplishments anyway.

In a video responding to Olbermann's post, she recorded herself showing off her trophies for several of her accolades, including All-SEC first-team, three SEC titles, a second-place finish nationally, an SEC community service award, an SEC female scholar-athlete of the year and others. She also qualified for the U.S. trials for the Tokyo Olympics.
