Sam Bankman-Fried arrived in a federal courtroom in Manhattan on Tuesday for his arraignment, where he is expected to plead not guilty to criminal charges that he cheated investors in his now-bankrupt FTX cryptocurrency exchange. Bankman-Fried is accused of looting billions of dollars in FTX customer deposits to support his Alameda Research hedge fund, buy real estate and make millions of dollars in political contributions, in what prosecutors have called a fraud of epic proportions.
