There was an exchange where Comey explained what he was referring to when he told Trump (multiple times) that he was not personally under investigation which seems to be totally ignored by the media, and pretty much everyone it seems.
Comey said specifically in his testimony today that he was trying to assure Trump that he was not personally being investigated about the Steele Dossier (aka “pee pee tapes” and hookers) in order to not give Trump the impression he was in a “Hoover”-type situation where the FBI was in essence in a position to blackmail or hold that investigation as leverage against Trump.
Here is the exact exchange I am referring to above:
COLLINS: Did you limit that statement to counterintelligence invest – investigations, or were you talking about any FBI investigation?
COMEY: I didn’t use the term counterintelligence. I was briefing him about salacious and unverified material. It was in a context of that that he had a strong and defensive reaction about that not being true. My reading of it was it was important for me to assure him we were not person investigating him. So the context then was actually narrower, focused on what I just talked to him about. It was very important because it was, first, true, and second, I was worried very much about being in kind of a Jay Hoover type situation. I didn’t want him thinking I was briefing him on this to sort of hang it over him in some way. I was briefing him on it because, because we had been told by the media it was about to launch. We didn’t want to be keeping that from him. He needed to know this was being said. I was very keen not to leave him with an impression that the bureau was trying to do something to him. So that’s the context in which I said, sir, we’re not personally investigating you.
The entire framing and context of what Comey was saying to Trump was, we are not investigating you personally in regards to the Steele Dossier (aka “pee pee and hookers”) as a way for the Bureau to coerce you and have leverage against you.
