 Lawyers for Elon Musk are asking a federal judge to dismiss a lawsuit brought by former Twitter shareholders. As NPR's Bobby Allen reports, Musk denies he duped investors in his acquisition of the social media sites. Musk is fighting against a security fraud lawsuit alleging the billionaire waited 11 days to reveal his stake in Twitter back in 2022. Former Twitter shareholders say that delay saved Musk around $143 million and cost investors serious money.
