evidence: In general, classified documents must be handled in a way that protects the integrity and confidentiality of the information they contain. This includes securing documents in a safe or other authorized storage container when the documents are not being used by staff. If staff needs to move them from one place to another, they must follow security protocols to do so. Though classified information can be taken off the premises in the course of official duties, taking classified documents home is prohibited by executive order. [...] Mishandling classified information, especially if it is accidental, is usually handled as an administrative matter. However, more serious violations can incur criminal charges and penalties. Federal law (18 U.S. Code § 1924) states that anyone who "knowingly removes such 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 five years, or both."
