In an interview with Forbes, Donald Trump's dumbest son Qusay gives away the game: Even the ruse of Trump handing ownership of his companies to his own sons while in elected office, ownership that he will then reclaim after he leaves that office, was itself a con. Because Donald Trump will be getting personal updates on his businesses' performance on a regular basis.
“There is kind of a clear separation of church and state that we maintain, and I am deadly serious about that exercise,” [Eric Trump] says, echoing previous statements from his father. “I do not talk about the government with him, and he does not talk about the business with us. That’s kind of a steadfast pact we made, and it’s something that we honor.”
But less than two minutes later, he concedes that he will continue to update his father on the business while he is in the presidency. “Yeah, on the bottom line, profitability reports and stuff like that, but you know, that’s about it.” How often will those reports be, every quarter? “Depending, yeah, depending.” Could be more, could be less? “Yeah, probably quarterly.” One thing is clear: “My father and I are very close,” Eric Trump says. “I talk to him a lot. We’re pretty inseparable.”
So Trump has "separated" himself from the family business, except for the part where they're just keeping his chair warm for him and he's getting updates on the state of that business and maybe a few hints as to what the government might or might not do that would really help that business out.
