I don't understand, Trump uses the influence of presidential power, issuing private currency and selling perfume, and it's actually legal? Is there no such thing as using power for personal gain in the United States?

There is no president in the world like Trump, selling perfume, gold watches, mobile phones, virtual currency, dinner tickets... Many leaders of poor African countries are not so despicable. Trump's eating manners and personal ethics are so ugly that I don't know if it will be the last, but it is unprecedented.
