I’ll try to summarize what this is about. Putin’s chef Yevgeny Prigozhin, represented by counsel in DC is filing numerous things in the pending IRA case on behalf of his company Concord Management and Consulting LLC. (“Concord”). One recent filing was a motion seeking to hold Barr and Mueller in contempt for violating court rules about public statements. They claim that the Mueller Report states that Concord is essentially guilty. It’s a clever argument IMO.
So today the Govt filed something under the Classified Information Procedures Act (CIPA) that is allowing the court to see in camera material related to the case.
I explored a little and found the above linked US Govt filing. It says that a nearly fully unredacted copy of Vol I of the Mueller Report was to be delivered to the House and Senate intelligence committees on May 28, 2019.
My point is that I think it is possible that the document that went to the SCIF today for the judge was the minimally redacted Vol I of Mueller Report.
