General Discussion

It would probably require the victim to testify in some manner (behind closed doors to Congress presumably) and tell them that a) sex occurred with Trump, and b) Trump knew they were not 18. Just because, well, he's Trump and he fucking gets away with everything.

There is an angle he can use to weasel out here: While Guiffre has said that when she was "told to give someone a massage, that meant sex", it is also true that at the time she met her husband, she was in Thailand, on Epstein's dime, attending an actual professional massage seminar, like something on the up-and-up, legit massage training. She wanted to become a professional masseuse, and Epstein was paying for her to become one.

This fact suggests that there could, in fact, have been actual, regular massages going on at his estate, along with the happy ending kind. And IIRC, some other (then) girls have since said they "started out" just giving massages, without the sex part. Ergo, that will probably be "the angle" is that Trump got a massage, but it was just a massage, he didn't ask "the woman" for her identification.

Then there's also the angle that the DoJ had this information while Garland was in charge of the DoJ, and yet they "never said anything", which Trump will leverage to say "If they thought I did something illegal, they would've come after me!" and a LOT of people will come to that same conclusion when he says it, even though, in reality, they probably didn't "say anything" because they couldn't corroborate it with any victim's actual testimony, or other additional records, and the DoJ were actually a professionally-run organization at the time.

This is why I say that while it will look bad for him that he was "with an Epstein victim for an hour", the woman will need to tell Congress that Trump had sex with her, she was under 18, and Trump knew it, in order for there to be (maybe) something more serious happening to him than just embarrassment. And even then, we'll get at least some GQP creeps in attendance claiming "we didn't find her testimony credible", I mean, you could bet the farm that would happen in that instance.

MHO, fwiw.
