Thing is, to date, not only is that one the only single accusation of Biden ever having done anything illegal - in his life - there are no witnesses, no one and no evidence to substantiate her claim. Doesn't necessarily prove that she made it up, but all her co-workers from back then stated that it made no sense, no such thing that would seem to make it a possibility, and as far as they're concerned, she fabricated the story.

Nor do you.
You know who was destroyed? Jane Doe, 13 at the time she claimed Trump and Epstein violently raped her. She has a witness.
