Michael Woolf (who has a somewhat shaky track record) has alleged that there are photos in the Epstein files of Trump sitting around with topless young women on his lap, including one with the women pointing and laughing at his groin where a moist spot appears to be.
Wolff (it is an unusual spelling!) does have a track record on the more salacious details of a story.
It seems like he often gets a lot of things broadly correct and a few things perfectly correct, but other things completely wrong. I always take his stuff with interest, but also a grain of salt.
An excellent summary!
