I now fully believe the "Muller exonerates, then Huber prosecutes" theory. It makes too much sense for it to be otherwise.
We can probably deduce the timing of when the FISA is dropped if we go back in the crumbs and match it with that theory. I still believe it's dependent on the transcripts being released by the House, but it might line up with then Mueller ultimately writes his report.
One other thing, the first actual sort of movement from Mueller was when George Papadapolous pleaded guilty on Oct 5th, 2017.
Remember when "the calm before the Storm' was said?
It was the next day.
