So was JFK "John" or "Jack"? What a stupid thing to make an issue of.
As for a suit against the National Enquirer...
1. I haven't read the "article" but understand it was filled with words like "alleged" and "said to have". Words that would allow them to avoid a lawsuit. Also the "mistresses" were not named so there claims can't be proved or not proved.
2. Very few celebs have sued NE successfully for the false articles written about them. There have been a couple of exceptions (IIRC Carol Burnett was one) but it took several years and lot's of money.
3. Malice or libel towards a public figure if different than you or I. In the 1964 landmark case NY Times v. Sullivan (not that it makes any difference but in recent years after I have become a close friend with one of Mr. Sullivan's son) the Supreme Court ruled that to prove actual malice the plaintiff in a defamation or libel case must prove that the publisher of the statement in question knew that the statement was false or acted in reckless disregard of its truth or falsity. It's very hard to prove intent and why, including the cost and devotion of time, it seldom happens.
4. Who is Roger Stone? That's for a following post.
