RFK's final journey: How America stood by train tracks to say farewell
Sen. Robert F. Kennedy died 50 years ago today. "Bobby" Kennedy was assassinated at the Ambassador Hotel in Los Angeles just moments after he won the California presidential primary. Shortly after his funeral on June 8, 1968 at St. Patrick's Cathedral in New York, a train took his remains to Arlington National Cemetery outside Washington, D.C. Up to two million Americans interrupted their day to stand by the tracks and pay tribute to the man lying in the train's last car on its 225-mile journey. John Dickerson reports.
