Musk subpoenas Twitter whistleblower in buyout battle

Elon Musk has formally subpoenaed a Twitter whistleblower to share information about spam accounts at the social network, as the billionaire fights in court to back out of a massive buyout deal.

Musk has tried to pull out of the $44 billion agreement by saying Twitter misled him on the number of false accounts, or bots, prompting strong denials and a lawsuit from the social media firm.

The Tesla boss hopes that allegations made by the former Twitter security chief Peiter Zatko, about major security gaps and problematic practices at the firm, will bolster his case.
