So the position he now exposes the FBI to is:- Weiner had every right to have Hillary Clinton's emails on his computer. i.e. Hillary is not guilty in anyway for her emails, while secretary of state, to have landed up on Weiner's PC.
As Weiner must have every right to have Hillary Clinton's emails on his computer, nothing contained therein is classified, and all goes to her yoga classes, Chelsea's wedding and other innocuous personal stuff as Hillary swore to under oath to congress - THUS Weiner is free to publish every email contained therein.
Pundits suggest Donald Trump has nothing to do here, as this last Comey announcement, rather than absolve Ms. Clinton, will carry him happily to the needed electoral votes, to the Presidency.
All he has to do, is get up and say words to the effect "my oh my! So waddaya know?"
