There is the expression in English, "Birds of a feather flock together."
Clinton (Bill), Trump, Prince Andrew, etc. seemed to be "friends" with this guy.
No one can tell me that being that close to someone, staying at his place, his island, his jet, etc. can say with a straight face that you know nothing about what is going on.
It would be like being around El Chapo and saying you had no idea he was in the drug business.
Come on now, come on.
