In the 1993 book Lost Tycoon: The Many Lives of Donald Trump, the author wrote about divorce depositions between Donald and his first wife Ivana in which she alleged that he raped her.

The Daily Beast summarized:

After a painful scalp reduction surgery to remove a bald spot, Donald Trump confronted his then-wife, who had previously used the same plastic surgeon.

” ‘Your f[******] doctor has ruined me!’ Trump cried.

“What followed was a ‘violent assault,’ according to Lost Tycoon. Donald held back Ivana’s arms and began to pull out fistfuls of hair from her scalp, as if to mirror the pain he felt from his own operation. He tore off her clothes and unzipped his pants.

” ‘Then he jams his penis inside her for the first time in more than sixteen months. Ivana is terrified… It is a violent assault,’ Hurt writes. ‘According to versions she repeats to some of her closest confidantes, ‘he raped me.’

“Following the incident, Ivana ran upstairs, hid behind a locked door, and remained there ‘crying for the rest of night.’ When she returned to the master bedroom in the morning, he was there.

“As she looks in horror at the ripped-out hair scattered all over the bed, he glares at her and asks with menacing casualness: ‘Does it hurt?’ Hurt writes.

While Trump’s lawyer, Michael Cohen, asserted that one can’t rape their spouse, Ivana has also walked back the allegations in subsequent years. She explained, “Mr. Trump and I had marital relations in which he behaved very differently toward me than he had during our marriage. As a woman, I felt violated, as the love and tenderness, which he normally exhibited towards me, was absent. I referred to this as a ‘rape,’ but I do not want my words to be interpreted in a literal or criminal sense.”
