I know Trump claims to have banned him, I'm not sure that there is any evidence that that is true. Trump has a history of changing what he says about history depending on current circumstances. Certainly the two had a falling out over real-estate.
I have no doubt that you are right about all those connections. I could play the same game, and find a list of conservative connections too, but I won't.
The original meme, said tongue-in-cheek that "I just want orange man bad", but talking about Epstein and Trump is really throwing stones in a glass house. The two were quite good friends and Trump himself has a history with women that has some alleged - let's just call it bad behaviour. Yes, so does Clinton, I know.
Why the president of the United States in participating in promoting a conspiracy theory about his death, I don't know - that's just weird. The meme world seems to have taken it up wholeheartedly.
