Actually after writing this I learned that Clinton requested all documents about himself. That IMO further backs that this isn't some kind of Kamikaze move to destroy trump, not it isn't a 4D chess move counting trump won't do it and that he is simply convinced there's nothing incriminating about him in the files.
I don't hold any special sympathy for Clinton and if he did those things I'm all for him dying in jail, but if there was something juicy about Clinton I think trump would already use it instead manufacturing evidence (like apparently the picture with him and MJ was an event not connected to Epstein).
