The gross negligence has to be willful to cause harm. There is nothing in the circumstance of any server containing State Department emails that harmed the USA. There was some talk that the FBI was tracking down a potential breach due to Russian hackers, but, that is not gross negligence. Hacking is a crime against the USA. It has nothing to do with anything that is relevant.
Hillary Clinton would never do anything to harm the USA. Never.
