Dozens of students at Indianas Notre Dame University protested White House policies on Sunday by walking out of a commencement speech by Vice President Mike Pence, who criticized political correctness at American colleges.
The members of the graduating class -- dressed in cap and gowns together with some two thousand classmates -- stood up and quietly left the school's football stadium when Pence began delivering his speech, videos posted online showed. Others cheered and some booed.
