Mark Shriver, president of Save the Children Action Network in Washington D.C., discusses his book, Pilgrimage: My Search for the Real Pope Francis, his intimate biography of the Pope, based on interviews with the friends, family and colleagues who knew him as Jorge Mario Bergoglio. He follows Francis’ journey to the papacy, and examines the origins of the pope’s humble and unpretentious style that has drawn admiration from Catholics and non-Catholics around the world.
