So, we know that information in emails found in HRC's account contain information that is currently classified.
We don't know if it was classified at the time it was placed on the server.
We don't know if HRC knew it was or would ever be classified.
We don't know if this information was ever accessed by anyone other than HRC.
We don't have any evidence this information was ever disclosed to anyone who it was not permitted to be disclosed to.
Don't get me wrong, I don't love HRC and don't put it past her to do underhanded things, but Republicans, who don't have many relevant facts are jumping the gun and have already convicted her in their minds. Many of them have convicted her of anything they can imagine she might have done, its how the Republican scandal machine works. They investigated Bill Clinton his entire presidency, until finally one of those investigations turned up a personal affair. An affair that occured years after the investigation had begun, and used that investigation to expose the affair and to set him up for charges related to trying to keep the affair secret. This appears to be the same thing, they were spending years and billions of dollars investigating her on Benghazi and in do doing found an unrelated practice HRC was engaged in as to how she stored her email. When it became clear they had nothing with the Benghazi investigations they leapfrogged onto this.
I wont call it a false scandal yet, because all the facts are not yet known, but as of now it has all the hallmarks of a product of the Republican false scandal machine.
