Remember the FBI interview of Huma? They showed her a message, and told her they believed it was Obama, using an alias.
She said: "how is that not classified?"
I’m not sure what emails State held, but this is Podesta and Mills discussing Obama emails on Crooked Hillary’s server - and coordinating with the White Hut about what to do with them.
This could be a smoking gun that Obama de facto authorized her private server.
