David Nasaw on "The Patriarch"

Joseph Patrick Kennedy was not only the patriarch of one of America's great political dynasties, he was at the center of many defining moments in American history. For years Joe Kennedy has been remembered for his philandering ways, anti-semitic views and pushing his children into politics. He has taken on almost a mythic villainous reputation and become a nasty footnote in history. How much is true? Tune in this Sunday evening when Al is joined by award winning biographer, Davis Nasaw. In his new book "The Patriarch" Nasaw unveils another side to Joe Kennedy and dispells much of the myth about the man.
