At the risk of going back on topic, was there ever a definitive reason given for Comey's dismissal? I don't pay close daily attention to the antics in the Trump government, but from what I can tell there have been several reasons given. That in itself is kind of weird, isn't it?
One responder mentions "...at the pleasure of the President...", which may be technically true, but that's just a cute way of saying who it is that appoints that position. It can't really mean that the person in the job is there at the whim of whoever is currently President, can it? That only happens is the kind of banana republic we used to make jokes about.
I also read somewhere above something about the dignity of the office. What a howler, thanks for the comic relief. You have a guy in office who brags about grabbing pu**y, speaks of his daughter in sexual terms, and encourages crowds to chant "lock her up" during political campaigns, and NOW you want to bring dignity and respect back? To mangle a couple of metaphors, that ship sailed months ago, and all the horses left the barn and they ain't coming back.
