Although Kennedy's role in the car accident that took the life of Mary Jo Kopechne, a young worker in Robert Kennedy's campaign, helped destroy his presidential hopes, he went on to become one of the longest and most productive senators in the country's history, serving 47 years until his death from brain cancer in 2009. Rep. Anthony Weiner, the most recent politician embroiled in a sex scandal, has said he isn't resigning despite acknowledging he sent sexually charged photos and messages to women. (AP Photo/File)
