Of course it is possible he ensnared some foreigners, and sure why wouldn’t he trade that info - not just for leniency upon his arrest but for advantage the entire time. Imagine the kind of high extortion you could pull off if you are in a very high office dealing with foreign governments and you have a very convenient Foundation in which to collect foreign contributions.
Actually take that one step further - I imagine that just about the only people who could take down a billionaire pervert blackmailer of the powerful would be people in very high office. So why wouldn’t he pay them off by giving them the blackmail info so they can run it themselves? He protects himself by cutting them in.
