Update: There are countless investigations ongoing and as it relates to this reopen of the Hillary case:
New emails found on a government official’s device, likely Huma Abedin tied to the FBI’s Clinton inquiry were discovered during the investigation into Anthony Weiner’s sexting.
It appears there are countless emails coming into evidence that are the cause of the House Oversight Committee and the FBI may be re-opening the email/server investigation. Given the handful of days remaining before the general presidential election, it is assured that something significant has come to the surface that would approve this decision.
