Conflict of interest is a stunning example. Under sustained pressure from left, right and mainstream media, as well as a broad spectrum of politicians, Hillary was forced to commit to divesting the family charitable foundation. In the interim foreign and corporate contributions, were curtailed. This is a foundation that has saved thousands of lives, and helped millions. None of the Clintons received any compensation from the foundation.
Contrast this with the far flung Trump business empire. Rather than building a wall along our southern border, he should build a Chinese wall between himself and the business. Instead his laughable plan is to have his children run the business. Going for an even bigger laugh, he has made his children special advisors to the president with top secret clearance. They also serve on the transition team, staffing the new administration.
The potential for conflicts is legion. Suppose they lack their father's golden touch. In return for investment capital or a favorable loan from foreign player, they influence policy. To gain access corporations need only agree to hold a major conference at a Trump property.
Good times are no shield. The most insidious threat is trading state secrets for financial advantage. Suppose they meet with Russian officials as representatives of our government. At the same time they ask for favorable terms, on building a hotel in Moscow.
Holding President Trump to a high ethical standard is not an attack, but rather appropriate respect for the office of the presidency.
