40 years later, Rep. Speier looks back on Jonestown horror

This weekend marked the 40th anniversary of the Jonestown massacre, in which more than 900 followers of Jim Jones were victims of a cult mass murder-suicide in Guyana. Among the survivors was Jackie Speier, now a Democratic congresswoman from California. She joins Judy Woodruff to discuss her new book, “Undaunted: Surviving Jonestown, Summoning Courage, and Fighting Back" and current politics.
