Elon Musk is terminating his $44 billion deal to buy Twitter, according to a new Securities and Exchange Commission filing.

"Mr. Musk has sought the data and information necessary to 'make an independent assessment of the prevalence of fake or spam accounts on Twitter's platform'" and did not receive it, the filing stated.

Fake accounts have become a sticking point in Musk's rollercoaster bid to acquire the social media platform, with the Tesla CEO previously threatening to end his agreement over concerns about the prevalence of bot and spam accounts.
