Tesla CEO Musk facing defamation trial for 'pedo guy' tweet

Elon Musk is going on trial for his troublesome tweets in a case pitting the billionaire against a British diver he allegedly dubbed a pedophile. Vernon Unsworth, who helped rescue youth soccer players trapped underwater in a Thailand cave, is taking his defamation case against Musk to jurors today in Los Angeles federal court. Musk, who later apologized and removed a tweet calling Unsworth a "pedo," says the term was slang for "creepy old man" when he was growing up in South Africa.
