Rosenstein, who is incredibly corrupt, signed the June 2017 FISA warrant to spy on Carter Page one month after he appointed Robert Mueller as special counsel so he really has no room to talk about principles.
Exactly what Rosensteins’ role was, is not fully known.
Q was purposely ambiguous in this regard.
Rosenstein said the one FISA warrant he signed was not the one made public. It was very educational to watch RR’s farewell ceremony at the DoJ with Barr, Sessions, RR and others yukking it up and having a great time together. Unimaginable that Sessions, Barr, etc could be having such a good time with say, Comey, Lynch, Holder, Yates, etc. There was genuine mutual good will and camaderie.
