The Atlantic: Donald Trump’s Conflicts of Interest: A Crib Sheet. “A semi-comprehensive list of the business concerns that may influence the president during his time in office.” By Jeremy Venook. Published Apr 24, 2017.

“As early as 2000, he was speculating that he “could be the first presidential candidate to run and make money on it“ by patronizing his own businesses and running the campaign out of one of his properties. During his 2016 bid, he did exactly that, establishing his political headquarters in Trump Tower (and quintupling the rent as soon as he became the Republican nominee and began drawing funds from the party rather than his personal war chest). Shortly before his victory, The Wall Street Journal reported that Trump’s campaign had paid out the unprecedented sum of more than $14 million to his family and companies for such services as flights on his personal airplanes, rent at Trump Tower, and meals and hotel rooms at other Trump buildings.”
