In 'Preaching To The Chickens,' Rep. John Lewis' Childhood In Full Color

Rep. John Lewis, a Democrat from Georgia, has long been a powerful voice for the civil rights movement. He was one of the leaders of the 1965 march from Selma to Montgomery and made a keynote address during the March on Washington.

But where did Lewis' voice and activism come from? That's the subject of Jabari Asim's new book for children, "Preaching to the Chickens: The Story of Young John Lewis."
