Evidence ... you know, like people and pictures corroborating that they were together ... people and contemporary complaint filings that show persons making the accusations were not silent at the time ... and, oh yeah, Cuomo's half-assed admission.
The accusations against Trump were all placed decades in the vaguely-dated (if at all) past so that they were almost impossible to fact-check. IOW carefully crafted to preclude Trump from defending himself by showing, e.g., he was not in NY at the time (though one false accuser made the mistake of claiming the supposed assault happened on an airplane model the airline she named had never flown). B-F tried the same vague-time-in-the-distant-past story-crafting in her false accusation against Kavanaugh.
