Riley Gaines 'ambushed and physically hit' after Saving Women's Sports speech at San Francisco State Riley Gaines was barricaded in a room on the 3rd floor of a university building for nearly three hours after the protests began Kyle Morris By Kyle Morris | Fox News

Former NCAA swimmer Riley Gaines was barricaded in a room at San Francisco State University Thursday night after she was physically assaulted following a speech to students about saving women's sports at a Turning Point USA and Leadership Institute event on the campus.

Louis Barker, Riley's husband, said he had brief conversations with her while she was barricaded in the room for nearly three hours.

"She told me she was hit multiple times by a guy in a dress. I was shaking. It made me that mad. It makes me sick to feel so helpless about it," Barker said. "She was under police protection and was still hit by a man wearing a dress."

On Twitter, Gaines shared footage she took showing her being rushed out of the venue by police officers amid an onslaught of verbal attacks from the detractors who surrounded her.

"The prisoners are running the asylum at SFSU...I was ambushed and physically hit twice by a man," Gaines wrote in the tweet. "This is proof that women need sex-protected spaces. Still only further assures me I'm doing something right. When they want you silent, speak louder."

While Gaines spoke to the students, many of whom expressed opposition to her viewpoints, other footage from the event showed the swimmer's remarks being drowned out by a group of pro-trans protesters who had become increasingly loud outside the room.

"Tonight, Riley Gaines spoke at San Francisco State University to share her personal story of competing against a biological male athlete, Lia Thomas, at the Women’s NCAA Swimming Championships last year," Eli Bremer, Gaines' agent, said to Fox News Digital in a lengthy statement.

"In the past year, her goal in speaking at universities has been to educate her peers about her experience and what the impact of the growing number of biological males in women’s sports will do to the integrity of Title IX. She has been questioned in civil and somewhat uncivil manners about her views many times, and she thoroughly encourages diverse viewpoints and debate on this issue.

"Instead of a thoughtful discussion tonight at SFSU, Riley was violently accosted, shouted at, physically assaulted, and barricaded in a room by protestors. It is stunning that in America in 2023, it is acceptable for biological male students to violently assault a woman for standing up for women’s rights.

"This will not stop Riley from boldly educating people of the dangers of biological males in women’s sports. She will continue to speak the truth against the radical left that no longer understands the difference between men and women."

Footage shared to social media by Golden Gate Xpress, the school's student-run newspaper, showed a small protest emerge ahead of Gaines' arrival at the school Thursday evening.

Other pieces of footage from the outlet showed the protest growing in size – eventually becoming so chaotic that Gaines was escorted out of the room and down a hallway by police and barricaded in a separate room.

While she was being moved to a safer location, protesters were captured on video chanting various phrases along the lines of "go the f--k home" and "trans women are women" while placing transgender flags on the school's walls.

The outlet also shared images showing some members of the TPUSA staff being held up and escorted out of the venue amid the protests. Chris Trudell, the assistant dean of students, was reportedly seen trying to deescalate the situation.

In a statement to Fox News, a TPUSA spokesperson said the counter-protest to Gaines' speech was "organized by SFSU’s Queer and Trans Resource Center."

The spokesperson said the rowdy protesters outside the room "rushed in when the event was over."

Gaines, a 12-time All-American swimmer, became a national figure when she objected to trans swimmer Lia Thomas participating in women’s sports. Many athletes, such as former Olympian Nancy Hogshead-Makar, have warned that biological males have a clear advantage over biological women when they compete.
