Riley Gaines ‘ambushed and physically hit’ after Saving Women’s Sports speech at San Francisco State

Swimmer Riley Gaines says she was “ambushed and physically hit” and forced to barricade for three hours from a mob of trans-rights protesters who stormed her speech about protecting women’s sports.

The 12-time All-American champ — a former competitor of controversial trans swimmer Lia Thomas -— shared alarming footage of cops hustling her to safety late Thursday at San Francisco State University.

“Why are you running!” one of the protesters yells gleefully — before a short-haired activist jumps in front of her to scream abuse.
