Trump can make money the easy way by (a) selling stock at a high price, (b) posting a "tweet" which will make the stock market go down immediately, (c) buying back at a much lower price, (d) posting a tweet which will make the stock market go up again.
@helenS that is called insider trading, controlling the market, it is illegal. But SCOTUS said as long as it is associated with his job, it isn't chargeable.
@Thrust When did I ever say that what other people in power do is okay? You and your fellow MAGAs take too much for granted, sorry if I misunderstand your intention. No other president has ever profited as much from their office, particularly in a short 100 days.
