Epstein and Trump went to a party where Trump, allegedly, raped a 13-year old girl.
I haven't exactly followed the case closely, but last I heard the allegations had been disproven. I think there's enough to legitimately criticise Trump for - including sexual assault and rape - without having to rely on a story like that one.
On the other hand, it's quite clear that he knew Epstein was into underage girls and it doesn't look like he had a problem with that, given that he's spoken admiringly to the press before about his friend Epstein and how he "likes them young", whereas even the right-wing press reported that Clinton (which is why I assume Epstein has been raised as a spectre of the left's) seemed to sever ties with Epstein very abruptly and speculated that it might have been because he found out about the underage girls.
So, if this absolutely has to be weaponised, then I'm not sure it does the most damage to the left, as logger was no doubt intending.
Not proven or disproven, but the suit was filed and dropped twice. It probably isn't possible to prove it one way or the other.
