I personally think that the whole Mueller Gang was continuously surveiled through their whole tenure. It was the obvious thing to do. If that is in fact the case, then they will all go down hard.
It is just not the right time as we are just starting to fully disclose the whole attempted coup against Trump.
It should be obvious now that Trump and his forces do have all the evidence and are controlling the narrative. This leads into an impossible DEM political campaign for 2020. Weissman is no longer working at the DOJ. Curious, not!
