Tesla (TSLA) CEO Elon Musk sent a second letter calling off the $44 billion acquisition of Twitter (TWTR), according to a filing Tuesday.
Musk had already sent a letter in July, claiming the information provided by the social media giant was false and misleading.
Musk is "delivering this additional termination notice in the event that the July 8 Termination Notice is determined to be invalid for any reason," according to the filing.
