WASHINGTON — It was nearing midnight at the Trump International Hotel, and the president’s son was eating macaroni and cheese.

Enveloped in the smooth tones of jazzy hotel music, soft light from a million tiny chandelier crystals and the scent of candied bacon, Eric Trump, fresh from a rally this month in West Virginia, declined a question from a reporter and instead posed one of his own.

“Is everything perfect?” he asked, much like an attentive concierge.

From the Trump family’s point of view, how could it not be?

In this first tumultuous summer of the Trump administration, the hotel has cemented its status as a gathering spot for prominent conservatives and a place for the president’s supporters to see, be seen and curry favor with people in power, one $24 chocolate cigar at a time. (The selfies are free.)
