Florida Gov. Ron DeSantis blasted decorated transgender female swimmer Lia Thomas as a “fraud” Friday during a speech at Liberty University in Virginia.

Speaking to a supportive crowd of roughly 9,000 at the famous Christian college, the prospective 2024 Republican presidential candidate questioned the legitimacy of the former University of Pennsylvania star’s athletic feats.

“It is wrong to have a swimmer compete for three years on the men’s swim team, switch to the women’s team and win the women’s national championship,” DeSantis said to cheers. “That is a fraud. That is wrong.”
