It is a major revelation. If she actually used a classified system to send/receive information, it means she had SIPRNET and JWICS accounts. SIPRNET is the secure intranet used to transmit info up to/including SECRET and JWICS handles material up to/including TS/SCI.
With access to those systems, you get an e-mail account. So, if Hillary had acess to SIPRNET and JWICS, why use the home brew, unclass server to send classified material, up to TS/SI-GAMMA? Sadly, we know the answer to that one.
And the MSM is apparently “finished” with the e-mail issue. Not a single question at her presser on the tarmac this morning.
It's just too hard to write that kind of question down on the size of an average orange.
