Students at Duke University walked out on commencement speaker Jerry Seinfeld Sunday afternoon. Seinfeld, whose son currently attends Duke and whose daughter matriculated there, was delivering the commencement address as well as picking up an honorary degree. CNN estimates the number of graduating students who walked out to be around 30, while Reuters put the number in the dozens. Attendees in the bleachers also left. NBC News says a group of students with Palestinian flags could be seen in the aisle.
