I guess at the end of the day conservatives simply believe that corruption is in the eyes of the beholder. By many metrics Pruitt’s behavior is unethical and contradicts all the rhetoric about “draining the swamp”. But since he’s one of Trump’s boys the Trumpists will find little objectionable about Pruitt’s many misdeeds. They’ll likely immediately go to some whataboutism or just point blank say they’re fine with this kind of behavior.
