Elon Musk sued by former Twitter execs over severance

Four former top Twitter executives have sued Elon Musk in a bid to recover more than $128 million in unpaid severance.

In a lawsuit filed on Monday in San Francisco federal court, they allege Musk has not paid the severance since he bought the social media company, now called X, more than a year ago.

X is already facing a pair of proposed class actions claiming it owes rank-and-file workers who were laid off after Musk's acquisition at least $500 million in severance, and a third lawsuit by six former senior managers making similar claims.The company has denied wrongdoing.
