I'm kicking off with number five: either or both knew. Trump has said as much ("some of the girls were on the younger side") and Clinton can't not have heard the same rumors. I guess there's a sort of don't ask, don't tell policy among the rich and powerful.
We're going to know in the trial anyway. This is more of a panic-o-meter.
There have been three lawsuits against Trump started by one of Epstein's purported victims, who claims that Trump tied her up at Epstein's apartment and the two of them took turns raping her, when she was 13. The first two suits were dismissed because they weren't properly filed or served, but the third suit was withdrawn by the girl after death threats against her family. The filings included an Affidavit by one of Epstein's employees confirming the girl's account.
Trumpbots and Russian posters have been going bat**** crazy since the Epstein indictment dropped trying to deflect to the Clintons, but I think Trump faces the greater exposure.
The Clintons have always stayed on the right side of the law, and they know that if they sneeze the wrong way, there will be an investigation. But Trump has always thought himself above the law, and has never been careful in his private life.
I'm Canadian, within the past five years ago we had a case in Toronto, where a prominent Toronto television host was accused of beating and raping a woman. He got off on the charges, but numerous women came forward with similar stories, all involving beatings and rapes. It seems he gets off on really rough sex, and he claimed he thought these were "consenual" affairs. The CBC where he worked, claimed to know nothing of his behaviours and were shocked, shocked, I tell you, by the charges. Except that CBC management had ignored numerous complaints of sexual harassment by women who worked with him, and had to bring in an employment mediator to deal with the "toxic work environment" on his show.
My oldest daughter moved to Toronto in the mid 1990's, and worked in and around the movie/entertainment business in Toronto. When news of this man's arrest hit the news, and the CBC denied knowing about his sexual predilications or his abuse of women, she laughed, and said the first thing she heard when she moved to Toronto was to never be in a situation where she was alone with this man. That he was a PIG and she would end up seriously hurt or injured. Now if a 25 year old girl new in town knew who and what this guy was, how did people who had known and worked with him for 20 years, not have heard any of it.
This is why there is a #MeToo and #time'sup movement. Because people knew. They've always known about these kinds of men. And they let it happen because they were making an awful lot of money off them.
