Never could. He's a political hack.
IMO, he was told that "accidents happen", and "your wife and children are beautiful" directly to his face.
He went out there in July because Hillary Clinton wanted him to state...PRIOR to the Conventions...that there was no 'There', there.
He went out there the last week of October because Hillary thought she was in a bit of trouble...figuring once again, that Comey stepping out in that press conference.
'Admitting', at the worst, to a lapse in judgment, but that nobody was hurt. (Benghazi excepted) in the handling of emails...and they found NO INTENT OF ANY WRONGDOING"
But was he a WILLING accomplice?
