In nearly 50 years in the U.S. Senate, Kennedy compiled an impressive list of legislative achievements: on health care, civil rights, education and immigration.  From outside the Kennedy's house on Cape Cod, we're joined again by Sean Corcoran, senior reporter for WCAI. The Kennedy family legacy is far from exclusively American, however – it extends across the Atlantic to Ireland. We're joined by Irish politician and former Kennedy intern Mark Durkan, leader of the Social Democratic and Labour Party in Ireland, and one of the leaders of the power-sharing governments in Northern Ireland.
