Mr. Trump, who branded his rival “Crooked Hillary” and said she would go to jail if he were president, said in an interview with reporters and editors at The New York Times that he was no longer interested in pursuing Mrs. Clinton, in part because he wanted to heal the wounds of a divisive campaign.

“I don’t want to hurt the Clintons, I really don’t,” Mr. Trump said during the interview. “She went through a lot and suffered greatly in many different ways, and I am not looking to hurt them at all. The campaign was vicious.”
