Even before he was sworn into office, Donald Trump’s refusal to divest from his vast business empire posed an unprecedented ethical challenge. Within weeks of his election, prices were surging at Trump’s new D.C. hotel, which was mostly empty when my colleague Emily Jane Fox visited the Sunday before Election Day. Foreign diplomats were flooding the lobby, sipping Trump-branded champagne, booking ballrooms, and speaking admiringly of the hotel’s landlord, soon to be president. The hotel, which was initially expected to lose $2.1 million over the first four months of 2017, has instead turned a $1.97 million profit. And since Trump’s inauguration, the swamp of financial conflicts has only gotten worse.
