Former model Amy Dorris has accused President Donald Trump of sexually assaulting her at a 1997 U.S. Open tennis tournament, in an alleged attack that left her feeling “sick.”

Almost immediately after the news broke, Trump acknowledged the incident, alluding to it over Twitter, but refusing to comment on it. She is the 26th woman to stepped forward and accuse him of assault.

In an interview with The Guardian, Dorris, 48, alleged that Trump accosted her outside the bathroom on September 5, 1997.

Dorris, who was 24 at the time, had appeared right near Trump’s VIP Box. She accuses Trump of approaching her and forcibly shoving his entire tongue down her throat while pinning her against a wall and massaging her whole body sexually.

“He just shoved his tongue down my throat, and I was pushing him off. And then that’s when his grip became tighter, and his hands were very gropey, and all over my butt, my breasts, my back, everything,” Doris said.

“I was in his grip, and I couldn’t get out of it,” she said, adding: “I don’t know what you call that when you’re sticking your tongue just down someone’s throat. But I pushed it out with my teeth. I was pushing it. And I think I might have hurt his tongue,” Doris continued.

Doris corroborated her story with The Guardian‘s help, collecting documents like photos of Trump and Doris near one another and her U.S. Open ticket from that night.

Trump and his attorneys denied all allegations.
