Donald Trump has not given up interest is his businesses. He has only been willing to have his family run his business. This can lead to a conflict between his profits and the welfare of the country.
Why is this important?
Donald Trump has many business interests in other countries. Any gifts to his businesses or his family could violate the emoluments clause in the constitution. All American citizens should feel that the President of the United States must be above suspicion in any actions he takes on behalf of this country.
