Your dishonesty is, once again, becoming tiring. Had Hillary used a government server the investigation would be exactly the same. Why? Because classified info (classified prior or after the fact) on non secured systems is an issue regardless. You continue time and time again to ignore this fact.
The whole thing is a seamless & circular conflation of related but different issues.
Hillary's use of her private server for everything is one issue. That obviously wasn't illegal at the time or she'd already be busted. That's a complete no-brainer. It was clearly a mistake she's acknowledged.
The other is just how supposedly classified information made it to the internet at all regardless of where it came to reside. The IG who requested the security review could have slipped that knife between her ribs had she used state dept servers. That's not a secure system, either.
In any event, it's a good thing that the FBI only has to deal with the evidence rather than the Repub bullshit or they'd never be able to figure out anything. Brandolini's Law is clearly in effect.
