After the 1992 Rodney King riots in Los Angeles, the Rev. Cecil "Chip" Murray became a household name for his efforts to end the violence. Then-mayor Tom Bradley relied on his influence, and politicians of all stripes made sure to visit the First African Methodist Episcopal Church in Central Los Angeles. Earlier this month, a 75-year-old Rev. Murray delivered his last sermon as head of the First AME congregation. NPR's Tavis Smiley speaks with Murray about his activist past and his still-active future.
