WALL STREET JOURNAL: Why Trump Wins: Will Robert Mueller investigate intelligence agencies for playing in domestic politics?

The FBI, CIA and NSA are eager to pose as scrupulous, disinterested arbiters of Russian meddling. They are not eager to be seen as victims and patsies of Russian meddling. To use Mr. Comey’s phrase, the performance of our national intelligence directorate is the one rock that hasn’t been turned over.

So here’s a question for Special Counsel Robert Mueller, a former FBI chief himself. Will he accept the current framing that his Russia investigation is about everything except whether his former agency was semi-wittingly duped into some of its interventions by Kremlin danglings—there’s nothing to see here, move along.

Or will he have the courage to ask the requisite questions the FBI, CIA and NSA don’t want asked about their own, perhaps, gullibility and overeagerness to play in domestic politics because of their dislike of Mr. Trump?

Washington’s desire to get to the bottom of Russian meddling is probably less than you imagine. If not, the places to start are the Trump dossier and the role of Russian disinformation in promoting Mr. Comey’s intervention in the Hillary Clinton email matter.

I don’t think Mueller can be objective here. He should resign — or be replaced by someone without his conflicts of interest.
