A former model has accused Donald Trump of sexually assaulting her at the US Open tennis championship 23 years ago.

Amy Dorris, 48, who lives in Florida, said she felt ‘sick’ and ‘violated’ after the alleged assault in Trump’s VIP box at the tournament in New York on September 5, 1997.

Trump denies the claim.

In an interview with The Guardian, Dorris alleges that Trump forced his tongue down her throat and held her in a ‘tentacle’-like grip that she could not escape from.

‘He just shoved his tongue down my throat and I was pushing him off,’ Dorris said. 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.

‘I was in his grip, and I couldn’t get out of it. 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.’

Trump’s lawyers have denied ‘in the strongest possible terms’ that the president ever harassed, abused or behaved improperly towards Dorris.

The president’s lawyers told the Guardian that there would have been numerous witnesses to any sexual misconduct in the VIP box.

They also claim that Dorris’s ex-boyfriend Jason Binn has told them he has no recollection of Dorris making any such claims at the time.
