There should be no doubt now about Comey being part of the swamp.
Fire him, Trump.
It’s too late politically. Day one or two, no problem. (1st mistake) Comey’s admission of an active investigation into the Trump campaign provides him cover for a good while. Since Sessions recused himself (2nd mistake), that decision to approve the public release was made by the Deputy AG which is not a Trump appointee.
In my opinion, the only way Comey is fired now (would be a third mistake at this juncture) is if Trump or Congress (or some other means) brings forth information that shows Comey is complicit or incompetent. For example, if McCabe is complicit (reasonable) and Comey allowed it to happen under leadership, even if not having direct knowledge of it.
