As someone who uses the wonderful Wikipedia on a regular basis—in Hungary I don’t have the resources of English-language libraries—this article in USA Today (that bastion of all true knowledge) was particularly interesting.
John Seigenthaler, one of Robert Kennedy’s administrative assistants in the 1960s, as well as one of his pallbearers, was surprised when his son pointed out this Wiki-bio:
John Seigenthaler Sr. was the assistant to Attorney General Robert Kennedy in the early 1960’s. For a brief time, he was thought to have been directly involved in the Kennedy assassinations of both John, and his brother, Bobby. Nothing was ever proven.
John Seigenthaler moved to the Soviet Union in 1971, and returned to the United States in 1984.
