There is zero evidence that Trump "colluded" with the Russians. The only smoke we see emanates from the mouth of that interminable windbag named Mark Warner. Nor is there a scintilla of evidence that the Russians "hacked" anything. Not the DNC server. Certainly not any vote tallies in Michigan, Wisconsin, Pennsylvania or anywhere else in the USA. And there is no evidence the Russians hacked John Podesta's email either.
In the absence of evidence or anything that resemble probable cause, there is zero justification for a special prosecutor. Are you a shill of the Washington Establishment, Mr. Rosenstein? Yes, you were fooled by the news media and high-ranking government officials but so were a lot of honest people. We like to believe there are limits to their treachery, but these nefarious forces have no limiting factor to curb their deceit. Face the facts.
Time to correct your mistake, Mr. Rosenstein.
