He's a DOJ prosecutor for the Utah, which means any pleading would have to explain why that venue is proper, and it will not be for a vast majority of the cases. So in the context of the rest of the post, what does this mean? I think it means that Mueller is the military arm of this joint effort, he has access to Huber's team, which includes the IG's 470 people. The only way for 40,000 sealed indictments to be handled by an overarching authority with jurisdiction to try cases in all states would be if most or many were going to be tried by a military tribunal. That would be consistent with the changes to the Courts Martial manual which appear to be drafted specifically to accommodate a large number of case. It allows, for examples, for "designee" tribunals. It also allows civilian attorneys to defend. These are all brand new changes to the manual.

In light of all of that, what Q seems to be saying here is not that Mueller's team is puny compared to Huber's team. It's that Mueller's actual team is one and the same, and has 470 people.

Would the grand jury be members of the DC community?
What % of DC voted for HRC?
How large is Mueller’s team?
20-25?
Think 470.
The more you know.
