Tesla and SpaceX CEO Elon Musk filed suit against Musk and X Corp. on Monday, March 4, saying they are entitled to more than $128 million in unpaid severance payments. The executives claim they were fired without a reason on the day in 2022 that Musk completed his acquisition of Twitter, which he later rebranded X. X faces a “staggering” number of lawsuits over unpaid bills.
