Elon Musk Returns to Twitter and Raises Eyebrows

Aug.29 -- Elon Musk returned to Twitter to showcase the impulsiveness that’s raised the eyebrows of investors and regulators alike lately. In a series of posts Tuesday, the unpredictable chief executive officer denied that he cried during a New York Times interview earlier this month. Musk then couldn’t resist trading barbs with a follower who criticized him for calling a cave explorer in Thailand a pedophile back in July.
