Elon Musk calls Thai cave rescuer a 'pedo guy'

The verbal sparring between Musk and Vernon Unsworth, a cave explorer who helped rescuers pinpoint the location of the missing Thai soccer team, is over the child-sized submarine Musk sent to Thailand last week in an attempt to assist the rescue. Unsworth, who is an expert in the Tham Luang cave system, told CNN it was a "PR stunt" with "no chance of working."
