Pope Francis' decision to canonize the 18th century Spanish missionary Junípero Serra has drawn a strong protest from many indigenous groups. Serra founded nine of the 21 missions in California that later were the basis of what is now the modern state. Hundreds of thousands of people died after the missionaries arrived. According to historian Alvin Josephy, what happened in California "was as close to genocide as any tribal people had faced, or would face, on the North American continent." We speak to Valentin Lopez, chair of the Amah Mutsun Tribal Band. He's been leading efforts to oppose Pope Francis' decision to canonize Father Junípero Serra.
