I doubt any of this would have been public had not Judicial Watch filed law suits and demanded documentation, with a judge agreeing and ruling in favor of turning the emails over.
Had they gone with a Special Prosecutor none of this would be public today. I also find it strange the FBI is releasing information when it has withheld it in the past.
JW had a lot to do with it as well as the Benghazi committee. If Obama wants to clear the way for Biden, all he has to do is let the FBI and DOJ follow the law. The only fly in the ointment is that some of these emails could link the WH directly to the phony story of video being the cause of the attack.
