The priest who would become Pope Francis impressed his Jesuit superiors in Argentina from early on, taking on more responsibilities, sure of himself - until it became apparent that he had divided the Jesuit community - and he was sent away to a kind of internal exile that lasted two years. Mark Shriver, nephew of President John F. Kennedy, head of an international lobby network for children, former Maryland state legislator, discusses his new biography of the 266th pope. It's titled, “Pilgrimage: My Search for the Real Pope Francis.”
