What was amazing is that Trump told some mumbo jumbo about Cohen's Business he knew nothing about and wasn't involved in, while the guys' main business was being Trump's lawyer.
Trump apparently had a bunch of those crooks fly around the planet to make 'deals'. With half assed dictators or mob bosses to build a hotel/casino or whatever.
The extend of his involvement was usually a PR stunt with his daughter and slapping his name on a building through a licensing deal that Cohen, Slater, Kushner or any of the other 'businessmen' brought to his desk.
He didn't care about the details so he probably didn't know what was in most of those deals he signed anyway.
That's probably also why he is so worried about all the legal cases. Because he knows he doesn't know what he signed and what he could be held responsible for.
I think as Trump rightly let slip, his main business was Trump's business. By all accounts he did very little actual legal counseling for Trump. But it certainly aides Cohen and by extension Trump to sell to the judge and the soon to be appointed "master" that will be combing over the documents the feds captured to argue that he did.
I think your narrative has some likely truth to it in that he probably doesn't know the full extent of his exposure, but the picture we also get from almost every deal Trump has made, especially as he went international after his financial troubles, is that they are much more involved than just slapping some signatures on a licensing deal a proxy put together and doing PR stunts. Like Ivanka and Donald basically acting like contractors at times down to picking out furnishings and paint schemes, or Donald notoriously demanding that contractors go ahead and break certain laws and dare people to come after him. Like they did in New York, Chicago, Panama, or Mumbai.
He wouldn't be crying about the FCPA for the last decade if he didn't know how much of a risk it is for him and to these dealmakers he pays commission to like Kalpesh Mehta and likely Cohen. Or be flying out to places like Hong Kong to negotiate financing personally.
I think the idea that Trump didn't know what he was doing or incentivizing, or was completely ignorant of the criminality underlying these projects requires a major stretch of the imagination. I'd concede that for instance he probably doesn't know every single palm greased or shady advance sale to a Russian mafia boss or drug lord that Nogueira secured for Ivanka and Donald in Panama so they could go make the case to financiers that their property would turn a profit, but it's a stretch to think he didn't have some base knowledge or encourage the broad strokes of what went down.....Though in terms of the FCPA, that probably wouldn't even matter, since ignorance is not really an excuse, by design.
