A spokesman for the Trump Organization did not respond to a request for comment. Mr. Trump declined to respond to a question this week about whether his family business intended to take advantage of any of the tax breaks or other benefits included in the legislation.

“I don’t know,” Mr. Trump said at a news conference on Sunday. “I just don’t know what the government assistance would be for what I have. I have hotels.”

Many of these special-interest provisions would be impossible for a casual reader of the legislation to identify. For example, on Page 15 of the bill, there is a section with the title “Business Concerns With More Than 1 Physical Location.” It says this change in federal law will apply to companies that fit “a North American Industry Classification System code beginning with 72” — a reference that turns out to mean the hotel and restaurant industry.

The provision says that if a company owns multiple hotels, even if the overall hotel or restaurant chain has more than 500 employees — the limit to qualify for treatment as a small business — it will still be able to take advantage of the small-business benefits offered in the rescue package.

That means loans from the federal government worth up to 2.5 times the firm’s monthly payroll that will not have to be repaid if the company uses them to keep paying employees during any coronavirus shutdowns.

Representatives from the American Hotel & Lodging Association reached out to Republicans and Democrats to push them to insert the language, arguing that it would allow the federal assistance to cover an additional 33,000 hotels, with a total of about one million employees.

The large corporations that own the big brands — like Marriott or Hilton — would not be eligible. But any individual hotel, including from one of these brands, that has fewer than 500 employees would be. Many hotels are owned by franchisees.
