Yes he has. His lies to congress alone are so numerous that it's probably going to land his sorry rear end in jail. People have faced firing squads for lesser crimes than this jack ass has committed. I know your Trump hate consumes you, but to sit there and say that Comey has not been shown to be a liar is ridiculous.
You should be repulsed by the actions taken by the leadership of the FBI and the DOJ throughout this whole deep state charade that's been going on for over a year now. Most Americans are repulsed by their lies, their treachery, and their unfair investigation into the duly elected President of the United States, Donald Trump. They have torn this country apart to such a point that it may never recover and they've done it based on nothing BUT lies, and Comey is at the top of the list of LIARS.
Is the fact that Inspector General Michael Horowitz issued a criminal referral for Comey concerning his involvement in the potential crimes of PERJURY and obstruction of justice not example enough for you? Man, you really need to get your head out of your ass when it comes to what the corrupt deep state, DC establishment. That is your real enemy. It isn't the freedom loving patriots fighting against the corruption of the deep state that you relentlessly attack.
Just one of the Comey lies involves the dossier and where it came from. He said, under oath, he did not know where it came from. His book says something different. Only somebody with a naive crush on him would think he is an honest person and not part of the deep state.
That’s an iron clad defense.
I've always been partial to the Oliver North line.
"I was provided with additional input that was radically different from the truth. I assisted in furthering that version."
You're referring to Comey's lie(s) to Trump during that meeting, when he told the president-elect that the Republicans were responsible for the fake dossier?
Comey has since admitted he lied to Trump....knowing it was Krooked Killary and the DNC that had funded the fake dossier...because he didn't want to upset or get on the wrong side of the incoming POTUS. That was certainly plausible since many Republicans were never-Trumpers. Then, I believe, Comey repeated that lie several more times, including to a Congressional committee.
If he lied it should be easy to find.
