A little factual nitpick. There are multiple memos. The "loyalty" memo was leaked around March 11. The "obstruct Flynn investigation" memo could have been leaked later.
I agree that Comey's reason, "corroborating tapes" is nonsense. Something wrong with that boy's head.
-- ... when he gave his presser on July 5 last year, I knew for sure that he was a man without integrity. --
Many many people knew that, then and there. See Rosenstein letter - it's exactly what i was thinking. How DARE he usurp the prosecutor's job. If that was my immediate reaction, I guarantee you it was the reaction of thousands, maybe millions, who have a practical working knowledge of the relationship between the investigator (cop) and the DA. I bet half of the FBI was livid.
It is hard to know which memo different people are referring to since there were several leaks of memos mentioned in various publications. This usually shows to me that someone is trying to muddy the waters instead of making things crystal clear, for a specific purpose of wanting to confuse readers.
Another thing I think is worth noting is that Comey had reservations about Rosenstein. ***“Rod is a survivor,” he said. And you don’t get to survive that long across administrations without making compromises. “So I have concerns.”***

In that one statement about Rosenstein, Comey has admitted that he himself has had to make compromises in order to survive in DC. It’s one of those things that stinks about the Swamp.
