two problems ignored by Clinton fans:
1) Clinton when first approached about the existence of the server explicitly denied it's existence. Straight up lie.
2) as a government employee she was provided with a secure, official, and AUDITABLE email system to conduct business with. And chose to ignore it without any sort of series of complaints about the system or official reasons to demand repairs or configuration changes before then going off the reservation. WHY does a Highly Placed Federal Government Official want to conduct business away from any auditable or employer monitored channels? We all know the answer to that, but seem to only remember it when one Party uses that excuse.
