I'd say tentatively that I wouldn't call RR and RM white hats. RM's past especially excludes that, and if RR signed off on FISA warrants, that's it for him too.
They are now probably Trump's bitches though. That classified memo of August 2017 modifying the scope of the RM's investigation may have changed it to focus on Dems. (But how do the true white hats from Trump on down enforce them to carry out that investigation with vigor? Who oversees Rosenstein now, Trump himself?)
Thus, the reason possibly swampy judges are suddenly getting mad at the SC: the SC is hurting their friends.
