The Mueller investigation only exists to keep the false Russian collusion narrative alive. They have found nothing or it would have been leaked already and impeachment proceedings would be underway. The real collusion that is going on is between the democrats, the media, and establishment RINO Republicans that are attempting to stage a silent Coup to overthrow the duly elected President of the United States. The longer this goes on, the more it's going to cost the democrats in the midterms. What you are actually witnessing is the beginning of the demise of the democrat party.
