What evidence can he produce if he doesn’t know when the incident supposedly happened? That’s my point. What is he supposed to testify to? He can’t possibly refute any of her claims because he has no idea when it occurred.
Then he needed to testify to that. He could have testified. The thing I think you are tripped up with is civil tort standards are very different from criminal complaints. In this case is just the preponderance is the evidence. Considering trump failed to testify the jury apparently decided that there was enough evidence that sexual abuse claim was valid and that does not require an exact date and time which would be needed to show beyond a reasonable doubt.
