Michael Avenatti has pleaded not guilty to charges he defrauded his most famous client, Stormy Daniels. The embattled lawyer appeared before a federal judge in New York after surrendering to authorities earlier today. The indictment says Avenatti emailed a letter purportedly from Daniels to her literary agent. It instructed payments from an $800,000 book deal should be deposited into an account he controlled. Prosecutors say Avenatti used the money for his own business and personal expenses.
