Ironically (if it weren't so scary serious) it's Trump who was due to go to court over the rape of a minor together with his buddy Epstein.
Seeing as the case never made it to court, there's of course a chance that the accuser withdrew due to this not actually being true - there is also, however, an at the very least decent chance that this happened due to his position rather than her having changed her view about the incident (IIRC there was at least one lawyer saying she withdrew after having been threatened at the time).
As a rule of thumb: if Trump accuses Hillary of anything at all, there's a reasonably decent chance he's guilty of it himself. See recent use of private phone controversy. And, no, that's not to say Clinton is always innocent, just that he has a proven track record of accusing her of stuff he's himself at least under suspicion on.
