Carroll, now 75, is probably best known as an advice columnist for Ellemagazine.
In an interview with The Washington Post on Friday afternoon, Carroll reiterated the allegations, saying that during a chance encounter with the then-real estate developer at Bergdorf Goodman in late 1995 or early 1996, Trump attacked her in a dressing room. She said Trump recognized her from television and asked her advice on buying a present. She then claims Mr Trump was "forcing his fingers around my private area, thrusts his penis halfway - or completely, I'm not certain - inside me".
Trump denied the allegations Saturday, telling reporters as he departed the White House for Camp David, "I have no idea who this woman is".
Trump, in a statement, emphatically denied the incident.
"Shame on those who make up false stories of assault to try to get publicity for themselves, or sell a book, or carry out a political agenda - like Julie Swetnick who falsely accused Justice Brett Kavanaugh", Trump said. In her own article, she listed 15 women: Jessica Leeds, Kristin Anderson, Jill Harth, Cathy Heller, Temple Taggart McDowell, Karena Virginia, Melinda McGillivray, Rachel Crooks, Natasha Stoynoff, Jessica Drake, Ninni Laaksonen, Summer Zervos, Juliet Huddy, Alva Johnson and Cassandra Searles.
NY spoke with those friends, and noted that 'both still remember the incident clearly and confirmed their accounts'. Trump has denied all allegations.
In the article - an extract from her new book, What Do We Need Men For?
"'He raped you, ' she kept repeating when I called her". She says she pushes Trump off of her but keeps laughing so she doesn't seem uptight or she doesn't want to upset him or whatever her exact thought may be. They begin on the main floor looking at hats, and after some banter over a fur hat Trump sees the escalator and says, "lingerie!" or "underwear!" At some point, don't those people have to admit that they don't think the women are lying, they just don't care? Trump solicited Carroll's help in choosing a gift for an unnamed woman, and she wrote that she and Trump considered various items in the department store before he suggested they look at lingerie.
"I can't. It's hard to get rid of that", said Carroll. "Also, I am a coward", she wrote.
NY magazine noted that Carroll is the 16th woman to accuse Trump of sexual misconduct since he ran for president. "She is trying to sell a new book-that should indicate her motivation", he said in a statement.
She told two friends about the attack at the time, and NY verified her claim with both friends, who are journalists, but the White House denied Carroll's accusations. Trump also accused NY magazine of publishing Carroll's claims against him and others to boost its readership. When the tape became public weeks before the November 2016 general election, Trump said he never acted in any of the ways described on the tape, and said it was just "locker-room talk".
