From today's New York Times article on Judge Cannon, the partisan Trump- supporter, who has been assigned the Classified documents case:
Last fall, this reporter sought clarity on whether Judge Cannon’s involvement with the lawsuit meant she would be automatically assigned any indictment if it were brought in the Southern District of Florida. In email messages, the chief clerk of the court there, Angela Noble, wrote: “We do not assign related cases to the same judge. A related case will still be randomly assigned.”
Still, the odds of an indictment being randomly assigned to Judge Cannon were low. There are 15 active Federal District Court judges in South Florida, along with 11 on senior status who are still assigned to hear cases but at a reduced workload. Ms. Noble did not immediately respond to an email seeking clarification of what happened.
