Elon Musk on Monday mocked Twitter Inc's threat to sue him after it rejected a $44 billion takeover deal, tweeting that the social network needed to disclose more information about bots and spam accounts.

The series of tweets was the first public response from the head of Tesla Inc. since he announced Friday that he intended to reject the offer because Twitter violated several provisions of the merger agreement.

"Twitter's board must contemplate the potential harm to its employee and shareholder base of any additional internal data exposed in litigation," Benchmark analyst Mark Zgutowicz said.

Twitter plans to sue Musk as early as this week and force him to complete the deal, sources told Reuters.

The contract requires Musk to pay Twitter a $1 billion commission if he fails to complete the deal for reasons such as failing to fund the acquisition or being blocked by regulators. However, the commission will not be charged if Musk terminates the deal on his own.
