I buy it. We know about it at all because Glenn Greenwald felt like a crusader. Feinstein has released a statement Thursday afternoon acknowledging the existence of the letter. “I have received information from an individual concerning the nomination of Brett Kavanaugh to the Supreme Court. That individual strongly requested confidentiality, declined to come forward or press the matter further, and I have honored that decision. I have, however, referred the matter to federal investigative authorities,” she said. *Update: September 16, 2018 After this article was published, Dr. Christine Blasey Ford came forward as the author of the letter, charging Kavanaugh with sexual assault. Because the original text of the article noted that many aspects of the letter could not be confirmed at the time of publication, it has not been changed. Once Greenwald spilled the beans, she came forward because if she was gonna get dragged through the mud, better to be dragged face first.Update: September 13, 2018
