Assigning Mueller as Special Counsel should give everyone a chance to catch their breath. He was FBI chief for both Republican and Democrat presidencies. A stand up guy. Has unlimited funds and scope. Can subpoena, and submit even Trump himself to questioning. Probably better than a congressional investigation, because we stand a much better chance of impartiality, and less squabbling. Trump gets the thorough investigation he claims he wants. If he is cleared, this should suffice. An inquisition shouldn't be necessary afterwards.
Will Mueller get access to Comey's notes on Hillary as well? Lynch's too? He may dig up a truckload of skeletons.
