You sound a little behind on the case so I'll start from the beginning and you should go research from there. Enjoy the copy pasta, my friend. Hopefully you have an epiphany:

In addition to the State Department itself, these are the possible charges Clinton faces in just this investigation, not including the other three she's under:

1. Gross Negligence (remember, this does not require intent)
    Cloud storage which she was unaware of
    Unencrypted server
    Out of date security software
    Temporarily NO security software
2. Espionage (requires knowledge you're compromising security; also chargeable as Gross Negligence)
    The NSA told her it was unsecure
    Possibly gave classified information to Blumenthal, who had no clearance
    Discussed security issues with Blumenthal, and paid him, after the president explicitly forbid this
    Shared login credentials with many staffers, many of whom didn't have clearance
3. Obstruction of justice
    Deleted 30,000 emails without third-party inspection
    Attempted to delete the backups multiple times
    Claimed no backups existed
4. Perjury
    If any deleted emails were work related
    Claimed in 2012 that all emails on the server were erased, during the Benghazi hearings
5. Violation of the Federal Records Act
    If any deleted emails were work related
    Possibly even if they weren't

1. Violation of National Archive and Records Administration's regulations Improper storage of emails (including on their lawyer's flash drive) Making them less "readily available to access"
   1. Violation of Freedom of Information Act regulations Keeping the records private until two years after she left Claiming multiple times that the records no longer existed Her State Department only recording <1% of emails sent from anyone in the department
   2. Materially False Statements to federal agents Related to 7.3, in that she seemed to actively mislead Congress and the FBI by claiming ~90% of her emails were recorded by the State Department Pressuring a 3rd party to conspire in a cover-up*
   3. Conspiracy (under 18 U.S. Code § 371) She would almost certainly have known at least one of these was a crime
