Elon Musk has received a settlement demand from the SEC, which requires a monetary payment or possible legal charges regarding his 2022 Twitter stock purchases. Musk's attorney accuses the SEC of a prolonged harassment campaign and suggests the inquiries may have political motivations. The SEC has reopened an investigation into Musk's Neuralink as well, which adds to the ongoing tension between the billionaire and federal regulators, especially with a change in leadership expected following Donald Trump's upcoming inauguration.
