You may have seen some intrigue in the news recently. The Special Counsel’s office was arguing an appeal in Washington. The case was under seal, and the subject matter was so super-secret that the court didn’t just close the courtroom, it closed an entire floor of the courthouse so that no one would know who was arguing the case, which might allow inferences about the identity of the parties. The speculation was that the case involved a grand jury subpoena—grand jury proceedings are secret by design. Who could be resisting a grand jury subpoena connected to the Special Counsel’s investigation? The President? Someone else particularly juicy?
