The idea is to move beyond a focus on luxury hotels in big metropolises and build boutique properties in a broader mix of cities, including some the Trump brothers came to know well during more than a year of intensive travel, fundraising and grass-roots networking on the road to the White House.

“I got to see a lot of those markets on the campaign,” Donald Trump Jr., the president’s eldest son, told The Washington Post in a recent interview from his office on the 25th floor of Trump Tower. “I think I’ve probably been in all of them over the last 18 months.”

The expansion plan illustrates how President Trump’s political rise has the potential to affect his business even as he and his sons promise to adhere to a strict ethical boundary between the company’s moves and the Trump administration. And it shows the inherent challenge in separating the family’s political work from its corporate interests, with upsides and potential problems.
