It's hard to imagine what life has been like for Lee Harvey Oswald's widow for the past 50 years. Marina Oswald Porter started a new life, with a new husband, but understandably she has become somewhat reclusive as the decades have gone by. Anderson spoke to Priscilla Johnson McMillan, one of the few people alive who met both President Kennedy and his killer. She was a researcher for JFK when she was in her 20s, and later met Oswald while working as a reporter in the Soviet Union.
