Yes, Roy Cohn.
Here’s a brief clip talking about Trump and Cohn. It doesn’t mention Cohn’s homosexuality and that he died of AIDS, but that info is readily available if you want to google it.
I don’t get why his homosexuality enters into the picture at all. He was known for his lawyering and his connections in New York, including Barbara Walters and others. What are you really trying to say here?
