It is true that there is no concrete evidence (that has been released) that Trump is guilty of any wrongdoing in connection to Epstein or Epstein island. The source of the suspicion on the matter is rather the president's clear reluctance to allow the publishing of the Epstein files, which include images and lists of many visitors to the island who are complicit in Epstein's abusive behavior. This reluctance, in the public eye, makes him appear guilty. There is also no evidence that he hasn't done anything -- until more information is released, it is impossible to make a credible statement about his involvement. According to BBC, what we do know is Trump is mentioned in several documents related to Epstein's conviction and what happened on his private island, but it is unknown what is said about his involvement. The two operated in similar social circles and were close friends for years. According to the New York Times, in 2003, Trump gave a letter with a birthday greeting to Epstein, including sexually suggestive drawing of a naked woman and a reference to secrets the two men shared. The White House has denied that Mr. Trump drew or signed the note to Mr. Epstein.
All of that said, while it is clear the two men knew each other well and both have been accused or convicted of sexual misconduct, there is no concrete, public evidence of Trump's involvement in the atrocities of Epstein island.
