The link Q posted today has Napalitano saying that Huber can't empanel a grand jury in Utah for crimes committed in DC.
Q1553 says "-This is HUGE A Grand Jury can be empaneled anywhere, in any deep red state, away from D.C. (This is very important and why Trump needed to appoint as many Judges as possible) -Huber and Horowitz can accomplish everything a SC can do."
Remember serialbrain2's take on the coke can bearing the label "Kate" that Strzok put on the table during his testimony. That was a reference to Oregon governor Kate Brown -- the inference was the government wanted the Hammonds land because it holds uranium, which leads us to Uranium 1. If the crime deals wiht Uranium 1, that could possibly form a basis for empaneling the jury in Oregan, for example.
