ATLANTA— A former Toronto Star journalist has accused Donald Trump of sexually assaulting her when she interviewed him for People magazine in 2005.

Natasha Stoynoff, now an author, came forward with her story on Wednesday, joining at least three other women whose accounts of alleged assaults by the Republican presidential candidate were published the same day.

Trump denied Stoynoff's allegation of assault, as he did the allegations from other women.

"This never happened. There is no merit or veracity to this fabricated story," a spokeswoman told People.

Why didn't the writer of the twelve year old article in People Magazine mention the "incident" in her story. Because it did not happen!

— Donald J. Trump (@realDonaldTrump) October 13, 2016 The cascade of accusations poses a mortal threat to Trump's campaign, which was already nearing collapse in the wake of a newly revealed September 2005 video in which he boasted to an Access Hollywood host about kissing and groping women without their consent.

Stoynoff worked for the Star for about two years in the early 1990s, as a reporter and photographer, and later for People for two decades. She said that Trump assaulted her three months after the Access Hollywood video was recorded, when she went to his Florida home at the Mar-a-Lago club to interview him and his wife Melania about their first anniversary.

Stoynoff had been on the Trump beat for People since the early 2000s, she wrote, and always had a "very friendly, professional relationship."

"Our photo team shot the Trumps on the lush grounds of their Florida estate, and I interviewed them about how happy their first year of marriage had been. When we took a break for the then-very-pregnant Melania to go upstairs and change wardrobe for more photos, Donald wanted to show me around the mansion. There was one 'tremendous' room in particular, he said, that I just had to see," she wrote.

"We walked into that room alone, and Trump shut the door behind us. I turned around, and within seconds he was pushing me against the wall and forcing his tongue down my throat.

"Now, I'm a tall, strapping girl who grew up wrestling two giant brothers. I even once sparred with Mike Tyson. It takes a lot to push me. But Trump is much bigger — a looming figure — and he was fast, taking me by surprise and throwing me off balance. I was stunned. And I was grateful when Trump's longtime butler burst into the room a minute later, as I tried to unpin myself."

Stoynoff said Trump told her soon after, "You know we're going to have an affair, don't you?" The next day, she said, she was alarmed when a Mar-a-Lago massage therapist told her Trump had been waiting for her in a massage room before she arrived for an appointment he had helped to arrange.

In the September 2005 video, leaked on Friday, Trump told Access Hollywood host Billy Bush that he sometimes kisses women soon upon seeing them.

"You know, I'm automatically attracted to beautiful — I just start kissing them. It's like a magnet. Just kiss. I don't even wait," he said. "And when you're a star, they let you do it. You can do anything."

Stoynoff said she disclosed the incident to a People colleague and "a few close friends and family" but otherwise kept quiet, trying to convince herself "it was no big deal." She said she decided to speak out after she watched the Access Hollywood video and the presidential debate on Sunday, during which he specifically denied kissing and groping women without their consent and described his recorded comments as mere "locker room talk."

"I'm not sure what locker room talk consists of these days. I only know that I wasn't in a locker room when he pushed me against a wall. I was in his home, as a professional, and his beautiful pregnant wife was just upstairs," Stoynoff wrote. "Talk is talk. But it wasn't just talk in my case, it was very much action. And, just for the record, Mr. Trump, I did not consent."

On Wednesday night, Trump's campaign released a letter from his lawyer demanding the deletion of a New York Times article about the assault allegations of two different women.

"Your article is reckless, defamatory and constitutes libel per se," litigator Marc E. Kasowitz wrote to Times editor Dean Baquet. "It is apparent from, among other things, the timing of the article, that it is nothing more than a politically motivated effort to defeat Mr. Trump's candidacy."

Retired businesswoman Jessica Leeds, now 74, told the Times that Trump assaulted her when they were seated next to each other in the first-class section of a plane about 36 years ago. She said Trump lifted the armrest between them, grabbed her breasts, then "tried to put his hand up her skirt," the Times reported.

"He was like an octopus," Leeds said. "His hands were everywhere."

Rachel Crooks of Ohio told the Times that Trump assaulted her in 2005 when she ran into him near an elevator at Trump Tower, where she worked as a 22-year-old receptionist for a real estate company. When she shook his hand, she said, he would not let go, kissed her cheeks, and then kissed her "directly on the mouth."

A fourth woman, Mindy McGillivray of Florida, said Trump groped her behind at a 2003 Ray Charles concert at Mar-a-Lago, where she was assisting the event photographer, a friend of hers.

"All of a sudden I felt a grab, a little nudge. I think it's Ken's camera bag, that was my first instinct. I turn around and there's Donald," McGillivray told the Palm Beach Post. "He sort of looked away quickly. I quickly turned back, facing Ray Charles, and I'm stunned."

The assault allegations were not the only negative stories to emerge Wednesday about Trump's treatment of women.

Four women who competed in the 1997 Miss Teen USA beauty pageant told BuzzFeed that Trump walked into their dressing room while they were changing. In a 1992 Christmas feature on Entertainment Tonight, it emerged Wednesday, a 46-year-old Trump looked at a group of 10-year-old girls at Trump Tower, asked one a question, and then declared, "I am going to be dating her in 10 years. Can you believe it?"

MSNBC host Rachel Maddow said NBC's Today show would interview another Trump accuser on Thursday morning.
