Jack Worthington asked for DNA testing to substantiate his claim that he is the illegitimate son of John F. Kennedy. He states that his mother, who lived in Texas, was introduced to JFK by Lyndon Johnson. His mother has denied his story, and the DNA testing which has been performed, while not definitive, appears to indicate that he is not Kennedy's son.
