There is no doubt about it now, Hillary broke the state departments rules. At a minimum Hillary should have turned over all her emails before she left her job as secretary of state. They are the property of the U.S. She was never given permission to have a private server and if she had asked the answer would have been a definite no.
She has violated the Presidential Records Act. She had also stated that she got a legal opinion for this and again that was proven to be untrue. She has also stated that this will not affect her campaign at all and that there was no breach into her server. Will anything come of this; probably not, Hillary gets away again.
