To continue about what FBI Director Comey omitted where Clinton got her information to put on her private computer server(s). The US State Department uses SIPRNet Secret Internet Protocol Router Network to transit classified. When Hillary and her lackeys copied and pasted info from this classified network into her unsecure and unclassified personal computers, SHillary knew that they were taking classified information or should have very assumed they were. Comey knew this and he left it out of his statement.
Furthermore, messages are headed by the classification. You mean to tell me SHillary or her little lackeys didn't see this LoL?
Here is an example SPIRNet from Wiki. Notice a once "confidential" header/caption of a downgraded message.
The same secure computer network that Chelsea Manning had access.
