Tesla CEO Elon Musk arrives in court for defamation hearing
Tesla's chief executive, Elon Musk, arrives at a U.S. District Court in Los Angeles and is expected to testify in his own defense against a defamation lawsuit brought by a British cave explorer. Vernon Unsworth is suing Musk for calling him a "pedo guy." Musk posted the tweet after Unsworth accused Musk in a CNN interview of grandstanding by offering to help Unsworth's diving team rescue 12 boys and their soccer coach from a Thailand cave in July 2018. CNBC's Morgan Brennan reports.
