At Trump Hotel in Washington, Champagne Toasts in an Ethical Minefield

Conflicts that for months have been theoretical are now about to become real most immediately a possible challenge by the federal government. It owns the building that houses Mr. Trumps hotel and has granted him a 60-year lease. From the moment he is sworn in as president at noon Friday, Mr. Trump may be in violation of that lease, given a provision that appears to prohibit federal elected officials from renting the Old Post Office building, the Pennsylvania Avenue landmark that houses the hotel, from the government.
Guests at the hotel include foreign diplomats and politicians who could be looking to curry favor with Mr. Trump but even the act of paying their bills as they check out after the inauguration may open Mr. Trump to a challenge that he has violated the United States Constitution, which prohibits federal government officials from taking payments or gifts from foreign governments.
