The State Department has notified something like 130 current and former government employees telling them that emails that they sent to Hillary while she was Secretary of State have been retroactively reclassified as 'secret' and thus they are guilty of violating rules covering the handling of classified documents and are therefore subject to prosecution. And since Hillary received these now classified emails, she's also guilty of violating the laws covering the handling of classified material.
If Trump and his people get away with this, what's to stop them from retroactively create illegal activity so that anyone that they wish, they could prosecute and send to prison.
