But. there WAS no new information, and Comey himself admitted it. The FBI found mail, but who sent it, who received it, its contents, and its significance (if any) were, and still are, unknown. The investigation into that mail hadn't even begun with the necessary search warrant. Comey had a pig in a poke; except that even Comey didn't know what was inside.
In contrast, the FBI had been investigating Trump's connections with Russia (the leaked result is that there is little if any connection with Putin) and the source of Julian Assange's hacked email (it was probably Russia), but Comey refused to comment on THAT investigation because it might affect the election.  OK... so, that is one standard for Trump, another for Clinton.

Of course, we have known that Comey acts politically since he went beyond his authority to personally excoriate Clinton for "irresponsibility".  That far exceeded his job description, which is investigation, not judgement.
