Who really knows? Likely she had some trusted ghoul work all that our for her but I highly doubt anyone of that caliber had the credentials and authorization and wherewithal to implement a fully NSA-level secure system. At best, it might have been ‘commercially secure’ but that doesn’t mean much really beyond the key/number level of normal encryption, unless she went for the iPhone 6 stuff that the NSA is so pissed off about.
Backups? Who the heck knows? I’m betting NSA has it all, as well as the Chinese and Russians. Obama needs to cut loose of her very quick and throw her to the hounds and be done with it.
The problem is she was basically Obamas right hand man. Doing all his dirty work internationally. She can take him down if she wants. So the attacks on her will probably back off next week. They want her damaged enough to get a hard core progressive in the race who will continue the transformation of America as we know it. Hillary could care less about America. She is just in it for herself.
