In his memoir, “The Art of the Deal,” Trump wrote that his main focus as a youngster was “creating mischief.” As a second-grader, he wrote, he “actually” gave his music teacher a black eye because “I didn’t think he knew anything about music, and I almost got expelled.”

None of Trump’s childhood friends recall the incident or Donald talking about it then. Asked about the punch recently, Trump said, “When I say ‘punch,’ when you’re that age, nobody punches very hard.”

At a 2009 reunion, [classmate Donald] Kass said, the teacher, Charles Walker, told him that Trump had never struck him.
