The investigation appears to center around Musk's acquisition of Twitter, with allegations surfacing that Musk has been attempting to obstruct the SEC's efforts by refusing interviews and trying to 'distort' the investigation's focus. Various sources, including legal and tech news outlets, have reported on the filing and the accusations against Musk, highlighting the growing tension between the SEC and one of the most high-profile figures in the tech industry.
