According to six officials who attended or were briefed about the meeting, Mr. Trump then began reading aloud from the document, which his domestic policy adviser, Stephen Miller, had given him just before the meeting. The document listed how many immigrants had received visas to enter the United States in 2017.

More than 2,500 were from Afghanistan, a terrorist haven, the president complained.

Haiti had sent 15,000 people. They “all have AIDS,” he grumbled, according to one person who attended the meeting and another person who was briefed about it by a different person who was there.

Forty thousand had come from Nigeria, Mr. Trump added. Once they had seen the United States, they would never “go back to their huts” in Africa, recalled the two officials, who asked for anonymity to discuss a sensitive conversation in the Oval Office.
