Elon Musk is expected to give a deposition to Twitter under oath in Delaware, a Tuesday filing at the Chancery court in Wilmington revealed. 

The questioning for discovery of evidence is part of Twitter’s bid to prevent the tech billionaire from walking away from the $44 billion deal to buy the social media company that he had made back in April this year. 

The court filing revealed that the deposition would take place between September 26 and 27 but may stretch into September 28 if necessary

It is likely that Twitter will ask Elon Musk about his reasons for pulling out of the deal in addition to trying to find out why the co-founder of SpaceX has been asking for inside data. Twitter has accused him of trying to set up a competitor using the data. 

Another possibility is that Twitter’s legal team might try to ascertain how much of the funding for the $44 billion deal had Musk managed to secure thus far. That line of questioning matches with Twitter’s accusation that Musk is bailing on the deal out of economic concerns.

The world’s richest man, on the other hand, has repeatedly said that Twitter was not transparent about how bot and spam accounts were treated on the social media platform. In his countersuit, Musk has alleged that Twitter’s monetizable daily active users are about “65 million lower than what Twitter represents.” Twitter has denied these claims, calling Musk’s allegations “rhetoric-heavy” and “fact-free”.

Since August, the two sides have been exchanging a flurry of subpoenas with Twitter targeting some of the biggest names in Silicon Valley and Wall Street who have been associated with Elon Musk. In response, the tech billionaire has sent out subpoenas asking for information from senior Twitter executives like the former CEO Jack Dorsey. 

Several members of the Paypal Mafia have also been subpoenaed, including venture capitalists like David Sacks, Peter Thiel and Marc Andreessen.
