Um, what? Internal office communications aren't part of the official duties of Secretary of State? I don't even... wha... in any case, there were discussions with other diplomats among the emails turned over.
There were classified emails among the 30,000 that were turned over. And we don't even know that the emails from the privately-owned, privately-administered server were turned over in their entirety. We do know that the server was insecurely managed, for a certainty.
No, they are not which I assumed you knew since you already made the distinction with regard to Powell and Rice who used personal email for the exact same purpose. Official State business is conducted through letters, cables, personal meetings and phone. Not email
Classified emails were also sent to Powell and Rice so again -- you are the one trying to draw a non-existent distinction here which you have not explained if you don't see the difference between official correspondence and the emails in question. The situations are exactly parallel. What is it you think Powell was using his email for?
