Praised by John McCain as the "Last Lion of the Senate" Ted Kennedy has lived a life marked by both triumph and tragedy. In his new book, "Last Lion: The Fall and Rise of Ted Kennedy," Peter S. Canellos examines the life of the youngest of the Kennedy children, chronicling not only his incredible achievements in public service, but also his remarkable failures, like his expulsion from Harvard and the infamous Chappaquiddick scandal. Using past interviews from Ted Kennedy's closest friends and families, Canellos and a team of Boston Globe reporters write with rich insight the anecdotes which have made Kennedy's life so rich. Peter S. Cannellos joins Larry Mantle to talk about his illuminating new book.
