The lawsuit sets the stage for a legal battle between Twitter and the world’s richest man.

Musk’s attempt to back out of the deal has raised concerns about the social connection’s future.

Musk’s lawyers are expected to respond to Twitter’s lawsuit.

The legal showdown between billionaire Elon Musk and Twitter has officially begun.

Twitter accused Musk of breaching the agreement and called his exit strategy a “model of hypocrisy.”

At the time, Twitter said it planned to take legal action to enforce the agreement.

Musk made “unreasonable” requests but Twitter still tried to work with him to get him more information.

Under the merger agreement, Twitter and Musk have until Oct. 24 to complete the deal.

Shareholders would still need to approve the deal in a special meeting.

One tweet included ameme with actor Chuck Norrisin front of a chess board.

Twitter rebutted other arguments Musk is trying to make to end the deal.

The lawsuit also reveals that Twitter was suspicious that Musk was abandoning efforts to finance the deal.

“That needs to stop.”

The lawsuit was widely expected.

Over the weekend, Twitter called Musk’s termination of the deal both “invalid and wrongful.”

Potential outcomes include a settlement, a breakup fee and the deal being enforced.

The agreement between Musk and Twitter included a $1 billion termination fee.

Musk’s lawyer Mike Ringler didn’t respond to a request for comment.

After Twitter filed the lawsuit, Musk tweeted, “Oh the irony lol.”
