DALLAS (AP) - Two children of the late Robert F. Kennedy spoke in Dallas as a year of observances begins for the 50th anniversary of President John F. Kennedy's assassination.
Robert F. Kennedy Jr. and his sister, Rory, were interviewed Friday night in front of an audience in downtown Dallas.
Robert Kennedy says his father spent a year trying to come to grips with his brother's death after the assassination.
He says his father believed the Warren Commission, which concluded Lee Harvey Oswald acted alone in killing the president, was a "shoddy piece of craftsmanship." Kennedy says evidence is convincing it wasn't a lone gunman.
His uncle was assassinated in Dallas on Nov. 22, 1963.
Five years later, his father was assassinated in a Los Angeles hotel during his primary victory celebration.
