Re: "So Hillary was suppose to know what she was doing was wrong but not James Comey?"
The funny thing is that he offered a weak excuse, which reminded me of the weak excuse Hillary offered. Her excuse wasn't good enough to stop him from berating her before saying the FBI wasn't going to charge her, but apparently his excuse was good enough to keep using GMail.
Its the same "I know better than anyone else" attitude that let him overrule established DOJ guidelines and precedents by making public details of Hillary's email case while it was under investigation, berating her when he announced it was closed, announcing it was reopened a week before the vote, while not making details of Trump's already-ongoing Russian collusion investigation public.
Those DOJ rules exist to take the decision making of an individual out of it, so everyone is treated equally. Had both investigations been made public, or both remained secret, at least the treatment would have been even handed. But his "I know better" policy prevented even that. And yet there are still some republicans who claim Comey favored Hillary!
