Four top officers at the company have unloaded more than $100 million in stock since last month, reported ABC News. They include James Murdoch, the estranged son of right-wing media magnate Rupert Murdoch, and Elon Musk’s brother Kimbal Musk, who shed $27 million, according to a Security and Exchange Control filing.

As a “special government employee,” Musk’s appointment was only supposed to last 130 days, but there have been hints that President Donald Trump might want to keep him on longer.
