Elon Musk, the CEO of electric car giant Tesla, will face trial on Tuesday over allegedly manipulating the stock market with a tweet after a federal judge rejected his request to move the case out of California. The case dates back to August 2018 when Musk tweeted that he had sufficient funding to take Tesla private, causing a whirlwind in the company's share price. Musk was swiftly sued by shareholders for allegedly costing them billions of dollars with the Twitter post that said funding was "secured" to buy out the company's shareholders. After taking over Twitter, Musk fired more than half of the 7,500 employees, most in San Francisco, and radically changed the site's content moderation policies. The US stock market regulator, the Securities and Exchange Commission, ordered that Musk step down as chairman of the board of Tesla and pay a fine of $20 million.
