Mueller is probably kicking himself in exasperation the way this is all falling out but he has been the occasion of some very good work. Sessions’ recusal and Trump allowing an Obamanite to appoint M and then letting him continue when most of our guys were calling for him to fire the guy is all part of what Trump didn’t set in motion, but he understood the possibilities of it and being a canny New York successful developer and businessman, he kept it going and controlled the feed.
One of the reports I saw in the last couple of days suggested that Trump actually considered hiring Mueller to replace Comey. Take that for whatever you think it’s worth.
