Anon, the fifth floor shutdown was due to the court being moved from Article 3 to Article 1 and the discussion of classified materials. In short, Flynn went to something very close to a tribunal - as a witness/informant. Mueller has unrestricted territory to investigate government corruption.
Mueller is doing exactly what he is supposed to do, and that is introduce evidence to court. Giulliani is… I think, doing his part. The guy doesn't really register on my radar, and my gut tells me he's a stage extra. Could be wrong, though. In theory, NYPD had Weiner's laptop… So… That could put him in the territory of significant.
None of what is going on has anything to do with POTUS and everything to do with the deep state.
