Chief Judge James Boasberg of the Foreign Intelligence Surveillance Court has issued an Order. This order appoints Attorney David S Kris as "Amicus Curiae" to the Court. Mr. Kris is to review the FBI's response to the Court's demand. The FBI plans to avoid the debacle of "significant errors" disclosed in the Report of the DOJ Inspector General Michael Horowitz. The Foreign Intelligence Surveillance Act authorizes appointment of knowledgeable persons in connection with particular matters. A copy of the order can be reviewed here.
