Not wanting to be bound my an OFFICIAL determination of whether he should follow Session's lead and recuse himself from overseeing the Mueller investigation, Whitaker simply made an UNOFFICIAL "ask of DOJ instead of a formal request. As expected, the response from DOJ ethics was that he SHOULD recuse himself, which he promptly rejected. Not really surprising considering how he undermined his former boss (Sessions) to get the job in the first place. The DC "swamp" has now become the Trump "cesspool".
