'Full truth' of Khashoggi killing unknown, says UN official

A Saudi Arabian court has sentenced five people to death for their involvement in the killing of columnist Jamal Khashoggi. The proceedings lasted nearly a year and were shrouded in secrecy, with only a select group of diplomats in attendance and no press. William Brangham reports on Khashoggi's brutal murder, and Agnes Callamard of the United Nations joins Judy Woodruff to discuss the ruling.
