Musk is trying to walk away from the agreement.

The legal battle has raised questions about Twitter’s future.

The billionaire claims Twitter misrepresented or omitted information that would shed light on the company’s value.

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

Twitter and Musk are expected to head to trial on Oct. 17 if they don’t reach a settlement.

Twitter’s shareholders are scheduled to vote on the deal in a special meeting on Sept. 13.
