How Lincoln calibrated his moral compass

Abraham Lincoln was president of a divided country, and the lessons from his life might help guide America today. Jon Meacham is a Pulitzer Prize–winning biographer, the Rogers Chair in the American Presidency at Vanderbilt University and a fellow of the Society of American Historians. He joins host Krys Boyd to discuss his biography of the 16^th president, from birth to assassination, and Lincoln’s conviction that slavery must be ended as a moral evil. His book is “And There Was Light: Abraham Lincoln and the American Struggle.”
