A Mafia thug has claimed that President Donald Trump was recorded on camera at a New York City brothel allegedly having a threesome with a teenager and a pornstar back in 1982, and that the footage was later in custody of a mob boss.

The claim was made to authors Barry Levine and Monique El-Faizy in yet another tell-all book 'All the President's Women: Donald Trump and the Making of a Predator', which is scheduled to release on October 22.

Speaking to The Daily Beast, the authors revealed they interviewed former mobster John Tino, who claimed to have witnessed the incident at a luxury brothel he ran in Times Square. According to Tino, who is suffering from terminal cancer, a hidden camera in the room recorded black and white footage of the future president engaging in the sex act. However, Tino's story is to be taken with a grain of salt as he has a criminal record including forgery, fraud, and larceny.

Furthermore, Levine and El-Faizy were not able to find the alleged teenager or the porn actress identified in the book as 'Tri'.

What's more? The high-profile brothel Tino claims he ran has since closed down. "There are many people who will label Tino a liar and say his claims are false," Levine told The Daily Beast. "I came away feeling the allegations are believable."

According to Tino, Trump was known among them as "the real estate guy" who always "wore a tie and never drank alcohol."

He also claimed the real estate mogul would always ask for Tri. "Most of the women who worked there were porn stars, though not all," the authors wrote. "Trump preferred a woman who primarily performed live sex shows with her husband, though she acted in the occasional adult film as well."

Tino allegedly recalled how his Mafia boss once told him in the fall of 1982 "the real estate guy" was coming and that he had asked for Tri and another girl "for a ménage à trois." The gangster then described how a "young-looking female" turned up at the club and when Tri asked her how old she was, she said she was a "teenager."

That said, Trump would have been 36 and married to his first wife Ivana at the time this allegedly took place.

According to Tino, the secret cameras were installed to prevent prostitutes from being "roughed up" by clients. He allegedly took the video recordings and delivered them to his boss on a regular basis.

Unsurprisingly, the whereabouts of the videotapes are unknown to the authors. Also, they claim Tino's boss was murdered in 1986. Speaking to The Daily Beast, Levine said Tino had spoken to journalists during the 2016 election but nobody was able to track down pornstar Tri.

"To this day we don't know if the porn star involved in this alleged incident is still alive or whether she is dead," he said.

In response to the unsubstantiated claims made in 'All The President's Women', White House press secretary Stephanie Grisham told Business Insider the book was "trash." "That book is trash, and those accusations from 20 years ago have been addressed many times," she said.
