Plenty of proof exists, the same kind of proof used in a court of law. Is there forensic evidence? No, because rich, powerful men have a way of making sure women don’t talk, don’t report, don’t get police support. No other president in modern times (can’t speak for pre-media) has been accused of rape. Affairs? Sure-LBJ, Kennedy, Clinton. Not rape, and it’s credible with Trump. It should be very alarming but his supporters and those who believe Presidents should be able to act with impunity won’t call it what it is, or discuss it.
