Comey is all subterfuge and misdirection. He knew that Trump was in the right so he tried to insinuate, without actually stating the lie, that Trump might be dishonest and dirty. When he opted to "try to get a special counsel started" w/o doing it himself, it was an act of cowardice as he wanted someone else to do the dirty work as there was no legal basis for it. When he "leaked his memo (if it ever really existed), it was a fishing expedition to try to find out if Trump had a recording of the meeting, which would mean he had to be careful with his lies so he wouldn't commit new perjury. Now he tries to play the cowering/nervous/uncomfortable victim and claims that and his "pure intentions" justify his illegal leak - which put a "close friend" in hiding.
"Pusillanimous dastard" is one of the more apt descriptions of him....
