James Comey should be indicted and tried. There is clearly a case that he was a ringleader of the effort to depose Trump. From Andrea Widburg at americanthinker.com:
On March 20, 2017, then–FBI director James Comey told Congress that the FBI was formally investigating whether there were contacts between the Trump campaign and the Kremlin. We later learned that the alleged basis for this investigation was the Steele Dossier. Since then, we’ve also learned that the information in the Steele Dossier was fake.
The big question now is, when did the FBI know that the whole investigation, which severely handicapped Trump’s first term, was baloney? The answer, based upon newly released documents from the Senate Judiciary Committee, is that by mid-February 2017, Comey knew or should have known that the Steele Dossier was a hoax perpetrated by the Hillary campaign.
To go back a step, we know from Inspector General Michael Horowitz’s December 2019 report that the FBI relied upon the Steele Dossier both to spy on Carter Page and to investigate the Trump campaign. The same report establishes that the FBI’s investigation revealed that Steele’s information came from a source who, in turn, got his information from yet another source. By March 20, when Comey announced that the FBI was looking into the Trump campaign, FBI agents on the ground had already stated that the primary source had no credibility.
