Elon Musk's lawyers have sent a subpoena to Jack Dorsey, co-founder

of Twitter, for the company's former CEO to join the legal fight over the purchase of the social network.

The subpoena was sent to Dorsey on August 19, but was made public last 

Monday (22). The intention of Musk's defense is to seek documents from the 

co-founder related to fake accounts or spams within the social network.

On the other side, Twitter has subpoenaed Musk's circle of people close to him such as

Silicon Valley investors, friends and financiers. The intention of the 

social network is to involve Tesla in the legal fight. According to court documents, the 

subpoenas request information and documents about in-person 

conversations, letters, emails, text messages, social media contacts and phone conversations.
