Ok well in that case there was a significant enough development to warrant a statement such as this. Something did happen. Whether that is something that was an email release, something new they found, their hands being forced due to internal insurrection so to speak, blackmail from WikiLeaks or someone else to do their job or they release the additional emails for them, etc we don't know. What we do know is they don't do something like this a week before a presidential election unless there was something significant going on.
Yep, my thoughts as well. I have no idea what that "something significant" might turn out to be, but there's clearly something going on that triggered them making it known that they are investigating further. Whether the investigation was previously technically closed or not, everyone had been told essentially the matter was closed. Now it turns out they have reason to dig further again. Who knows what they found. With the myriad of entanglements with bill clinton inc, the clinton foundation and other shady organizations, it could be anything.
