18 USC §1924. This statute states that any employee of the United States who “knowingly removes [classified] documents or materials without authority and with the intent to retain such documents or materials at an unauthorized location shall be fined under this title or imprisoned for not more than one year, or both.” Hillary set up a private server explicitly to do this.
18 USC §798. This statute states that anyone who “uses in any manner prejudicial to the safety or interest of the United States…any classified information…shall be fined under this title or imprisoned not more than ten years, or both.” Hillary transmitted classified information in a manner that harmed the United States; Comey says she may have been hacked.
18 USC §2071. This statute says that anyone who has custody of classified material and “willfully and unlawfully conceals, removes, mutilates, obliterates, falsifies, or destroys the same, shall be fined under this title or imprisoned not more than three years.” Clearly, Hillary meant to remove classified materials from government control.
