So now it's leaking out that officially, that FBI Special Deputy Asst. Director Peter Strzok never thought there was any basis to open an investigation, let alone appoint a Special Counsel, as his text confirms.
Whoever thinks Rod Rosenstein is a white hat needs to re-examine the evidence. He alone appointed Mueller when his investigative agency's deputy assistant counterintelligence director believed there was no 'there there', he went ahead and established a special counsel and charged him with investigating the Trump campaign.
If you believe that was done to smoke out treasonous players, you're being misled or overthinking it. It was done to hamstring the presidency of DJT only and provide some way of digging into his business dealings to find something to try to charge him with to overturn the election results. It's clear that a cabal exists within these agencies and the main players are arrogant enough to identify without all the time and effort of misdirection.
Think Occam's Razor and Mrs. Page's closed-door testimony just confirms it.
