If insider trading is proven true, what are potential consequences for Trump? Is such behavior a no-no even for presidents or he'll get away with it until his term ends?
After his term ends… I don’t know whether the law says that the insider trading exemption Congress has also applies to the Executive branch… but I’d fully expect the Supreme Court to say it does, if it got that far.
You'd need pretty solid proof he was colluding with others to place trades, and not just running his tariff policies as he saw fit with advanced notice given to his inner circle as some sort of courtesy.
I'd be surprised if anything could be made to stick.
