"Constitutional crisis" for firing FBI?'
The crisis the country now faces, due to recent revelations, is the evidence that the Federal Bureau of Investigations has been transformed into a corrupt, criminally partisan agency that committed the crimes of sedition, tampering with evidence, Obstruction, Aiding and Abetting criminal activity by protecting those who committed those crimes, Campaign law (illegally buying and using in a U.S. election a false report containing Russian-generated propaganda from a foreign agent through a company working for the Russians), and other crimes.
In short, the FBI has betrayed the trust of an entire nation, becoming an organization - a Federal Agency of the United States Government - led by criminals.
The leaders of this agency criminally aided and abetted the Russians by hiding their criminal activity, placed their loyalty in a political party and the specific leaders / members of that party rather than remaining loyal 1st and foremost to this nation.
It's reputation is forfeit, which unfortunately is not fair to the many honest, hard-working, dedicated, honest agents within the agency. Deputy Director Andrew 'insurance Policy' McCabe's testimony before Congress did nothing to change that, except to possibly make matters worse, resulting in more coming Subpoenas.
