After months of silence, President Trump responded on Friday to reports that the Trump Organization has employed dozens of undocumented immigrants by saying that he doesn’t know whether the organization does or not.

“I don’t know because I don’t run it,” Mr. Trump said when asked if he was confident that undocumented immigrants were no longer working at his golf courses. “But I would say this: Probably every club in the United States has that because it seems to be, from what I understand, a way that people did business.”

The New York Times first reported in December that Victorina Morales, a Guatemalan undocumented immigrant, and several others living in the country unlawfully, had been employed at Trump National Golf Club in Bedminster, N.J., where Mr. Trump was heading on Friday.

Many undocumented workers at other Trump properties, including resorts in Philadelphia, Westchester County, N.Y., and Jupiter, Fla., have come forward since then and said they were also employed using phony Social Security numbers and green cards.
