The Tesla and SpaceX CEO called Vernon Unsworth a "pedo guy" in a July tweet after the diver criticized Musk's proposed submarine rescue plan. Musk's tweet has since been deleted. He also apologized for the comment after facing criticism, including some from Tesla investors.
However, Musk appeared to revive the accusation in a Twitter conversation Tuesday after tech publicist Drew Olanoff, who uses the handle @yoda, mentioned the incident.
"You don't think it's strange he hasn't sued me? He was offered free legal services. And you call yourself @yoda … " Musk replied.
