Disgraced Hollywood movie producer Harvey Weinstein pleaded not guilty on Wednesday to a new sex crime charge in New York. Weinstein, 72, who had emergency heart surgery just over a week ago, appeared in a Manhattan courtroom in a wheelchair to enter his plea to a single count of committing a criminal sexual act. Speaking to reporters after the arraignment, Arthur Aidala, Weinstein's lawyer, said the alleged sexual assault behind the new charge was "almost two decades ago" and "at this moment I don't know much more than that."
