Elon Musk has subpoenaed advertising technology firms Ad Science and DoubleVerify as the tech billionaire continues to look for evidence that might help him walk away from the $44 billion deal with Twitter. 

In his quest to gain more information on the number of bot and spam accounts on Twitter, the tech billionaire’s team of lawyers have asked the two companies for documents and communications that the company might have had with the microblogging site. This includes any reviews of any accounts the two firms might have done, or even their participation in an audit of Twitter’s user base.
