In a letter to the company on Monday, Musk accused the company of breaching their merger agreement byresisting and obstructing his right to information about fake accounts.
The letter signed by Skadden attorney Mike Ringler states that Mr. Musk has the right to end the merger agreement.
The shares of the social media company were down.
The $44 billion purchase of the company by Musk was put on hold until he knew the number of fake accounts on the service. The move was thought to be a negotiation tactic for a lower price.
He said that his team would do a random sampling to calculate the number of fake accounts, but that wasn't true. There is no such thing as putting the deal on hold as Musk claimed.
In Monday's letter, Musk's lawyer disagreed with the company's claim that it is only required to provide information for the limited purpose of helping to close the transaction.
The letter says that Mr. Musk is entitled to ask for information and data about the consummation of the transaction.
Mr. Musk is suspicious that the company is withholding the requested data due to concern for what he will uncover.
According to the letter, Musk would agree to ensure anyone reviewing the data would be bound by a non-disclosure agreement and he wouldn't use any "competitively sensitive information" if the deal doesn't close
A request for comment was not responded to by the company.
