According to an Epstein email, Trump spent hours at Epstein’s house with a victim. This is where Epstein called Trump “that dog that hasn’t barked”.
In another email between Michael Wolff and Epstein, Wolf suggests that Trump has been on Epstein’s plane and at his house in such a way that Epstein could save Trump by keeping secret about it.
This is all in the context of Trump being uncharacteristically resistant to releasing files about Epstein, even pressuring Republican congress people to not do it; in the context where Trump openly said that Epstein likes them young; in the context where Trump has had many many sex scandals; and in the context where the Trump administration has moved Epstein’s coconspirator to a more comfortable prison.
It looks like Trump was either involved in Epstein’s crimes, or knew about them and kept silent when he should not have. It’s possible that Trump didn’t really do or know anything, and just doesn’t want Epstein or Maxwell to make him look bad.
