A photographer who attended some of those parties and wished to remain anonymous, said that the models were enticed to attend by being promised that “you’ll meet rich guys who will help you.”
And the attraction for the men “was young girls assuming they’d get somewhere.”
He claimed that the girls were as young as 15, and were “over their heads, they had no idea, and they ended up in situations,” the man told The Daily Beast, according to the report. “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. There’s always someone to pick them back up. Nobody wants to call home and say ‘Help me.’”
Trump would allegedly wander through the parties enjoying himself. “Trump was in and out. He’d wander off with a couple girls. I saw him. He was getting laid like crazy,” the photographer said. “Trump was at the heart of it. He loved the attention and in private, he was a total fucking beast.”

Andy Lucchesi, a male model who allegedly organized the parties and a Trump supporter, told The Daily Beast that “there was cocaine around. I never saw him do that. Donald Trump does not do cocaine. He’s in control of himself.”
When asked about the ages of the girls, Lucchesi told The Daily Beast that there were “a lot of girls, 14, look 24. That’s as juicy as I can get. I never asked how old they were; I just partook.”
There was no response from Trump’s team to the report, the latest of a series of tawdry scandals to dog the campaign in the final stretch of the election season, including allegations of sexual assault by Trump.
Trump has denied the allegations, in one case saying the accuser was not attractive enough for him.
