Robert P. Jones, author of the new book 'White Too Long,' talks about the history of white supremacy in American Christianity. His main focus is on the Southern Baptist Convention, the denomination in which he grew up. "There's so much work still to be done," he says. "White Christians have been largely silent ... and have hardly begun these conversations."Book critic Maureen Corrigan reviews two new novels: 'The Aunt Who Wouldn't Die,' and 'Blacktop Wasteland.'
