Reeling from the global fallout of the coronavirus pandemic, President Trump’s family business has cut back hotel operations, closed some golf courses and restaurants and shed dozens of workers — all while pushing to keep other properties open and promote them on social media.

In recent days, the Trump Organization cut staff from hotels in New York and Washington, halted new reservations at a hotel overlooking the Las Vegas Strip and closed golf courses in Los Angeles and the Miami area, according to people with knowledge of the matter. It also closed the Mar-a-Lago club in Florida, which normally would be at a peak right now, with regular seasonal visits by Mr. Trump himself.

The cutbacks, expected to continue in coming days, were a last resort, a company executive said, as the priority had been keeping thousands of employees and contract workers on the job. The company has a portfolio of more than a dozen golf clubs and at least partially owns or operates five-star hotels in Chicago, Hawaii, Las Vegas, New York, Vancouver and Washington, as well as Ireland and Scotland.

Generally, the company has folded the tent only when local authorities mandated it, despite a growing national urgency to limit social gatherings and close nonessential businesses. In an interview, Eric Trump, the president’s son who manages the family business, said the company was trying to limit shutdowns.
