Platte River Networks may be a perfectly legitimate company who had a contract with the State Department to provide maintenance services for the department's online systems and email accounts. Hillary may not have even known they existed. It's possible that they have copies of all of her emails. Remember: Hillary is not exactly tech savvy, having once stated that her server was secure because the Secret Service was guarding her house. The existence of Platte River Networks may be a big piece of the puzzle that Hillary failed to take into account.
Pray for email storage in a “cloud” as a silver lining!!!
I gotta wonder how many employees of Platte River Networks held an SCI clearance.
