Of course it is not OK, but the troubling thing is that I do think other officials and congress critters utilize private servers. There is total disrespect for the rule of law by all parties in government.
No, I was not referring to private servers. The meme put out by Hillary is that those other secretaries of state and President Bush leaked classified just like she did. The private server is a red herring. Any leaking of classified information onto an unclassified system, private server or not, is an infraction at the very least. If intentional it is criminal.
