Delaware Court of Chancery

Twitter sued Tesla CEO Elon Musk on Tuesday to force him to complete the $44 billion acquisition of the social media company.

Musk and Twitter have been bracing for a legal fight since the billionaire said Friday he was backing off of his April agreement to buy the company.

Elon Musk announced on July 8 that he will abandon his tumultuous $44 billion offer to buy Twitter after the company failed to provide enough information about the number of fake accounts. Twitter immediately fired back, saying it would sue the Tesla CEO to uphold the deal.
