If he runs into “any amount of strength, he walks away from you.” Mr. Trump’s former ambassador to the United Nations is describing how she plans to confront—and defeat—her old boss in the Republican presidential primary. “I’m not movable when it comes to what I believe, and I call you out like it is. He knows that.”
