Donald Trump played a central role in Manhattan parties in the 1990s in which underage girls and drugs were a common — if not central — part of the entertainment, the Daily Beast reported Monday evening. The Republican presidential nominee has pushed back against mounting claims of sexual assault in the three weeks since a video emerged showing him bragging about sexual assault in 2005.

The real estate mogul allegedly mingled with underage girls amid cocaine and rich, old men who were looking for sex from those girls, two men who said they were at the Trump-hosted parties told the author of a book on the modeling industry who has covered Trump since 1985. Trump, they said, was also having sex at the parties but it was not clear how old his partners were.

The parties, held in suites on the corner of the Plaza Hotel overlooking Central Park, came with a promise for the young women and girls: access to the older men who could play an important role in shaping their modeling careers.

The girls, who were as young as 15, were in “over their heads, they had no idea and they ended up in situations. There were always dramas because the men threw money and drugs at them to keep them enticed. It’s based on power and dominating girls who can’t push back and can be discarded,” one of the men, a fashion photographer whose name was not disclosed, told the Daily Beast. “There’s always someone to pick them back up. Nobody wants to call home and say ‘Help me.’”

The stories rely on numerous accounts that have seemed to damage Trump’s viability for the presidency. Following the 2005 video release and then a debate performance days later in which he denied assaulting any women, more accusers came forward with their own allegations.

“He was like an octopus,” Jessica Leeds, who claims that Trump invited her up to first class on a flight in the early 1980s before beginning to kiss her and attempt to put his hands up her dress, told the New York Times. “His hands were everywhere.”

The accusations span decades, from Leeds' until as recently as 2013. Accusers include a former “Apprentice” contestant who said Trump thrust his genitals at her in 2007; a People magazine reporter assigned to Trump who said the businessman pushed her against a wall in 2005 and forcibly kissed her; and a former Miss Washington beauty pageant contestant who said in 2013 Trump “continually grabbed my ass and invited me to his hotel room.”

All of the allegations were published by different news outlets. At least 13 women have accused Trump of groping them or assaulting them in the past.
