Agreed.
One major difference is the levels of security. My understanding is that Hillary's violations only included up to Secret. Trump's violations were the highest levels of classified material. Specifically, nuclear defense material.
Ergo, just like there are difference levels of other crimes such as homicide, there are different levels of classified material violations. I did one once; shredded a confidential document and forgot to record it. When I went looking for it, there was a discrepancy. A classified material violation. I got my ass chewed for that one. LOL
