Disclosure of Classified Information – 18 U.S.C. § 798
Safeguarding national security and state secrets is a fundamental priority of the United States federal government.
Under 18 U.S.C. § 798, a critical section of the Espionage Act, it is a severe federal crime to knowingly and willfully disclose, transmit, publish, or make available classified government information concerning cryptography, ciphers, communications intelligence, or foreign government communications.
A conviction under 18 U.S.C. § 798 carries severe federal penalties, including up to 10 years in federal prison, substantial monetary fines, and mandatory forfeiture of property and proceeds.
What Is the Statutory Language of 18 U.S.C. § 798?
“(a) Whoever knowingly and willfully communicates, furnishes, transmits, or otherwise makes available to an unauthorized person, or publishes, or uses in any manner prejudicial to the safety or interest of the United States or for the benefit of any foreign government to the detriment of the United States any classified information—
(1) concerning the nature, preparation, or use of any code, cipher, or cryptographic system of the United States or any foreign government; or
(2) concerning the design, construction, use, maintenance, or repair of any device, apparatus, or appliance used or prepared or planned for use by the United States or any foreign government for cryptographic or communication intelligence purposes; or
(3) concerning the communication intelligence activities of the United States or any foreign government; or
(4) obtained by the processes of communication intelligence from the communications of any foreign government, knowing the same to have been obtained by such processes—
Shall be fined under this title or imprisoned not more than ten years, or both.”
What Are Key Statutory Definitions Under 18 U.S.C. § 798?
To understand how federal prosecutors enforce 18 U.S.C. § 798, it is vital to examine its statutory definitions under 18 U.S.C. § 798(b):
-
Classified Information: Information which, at the time of an alleged violation, is, for reasons of national security, specifically designated by a United States Government agency for limited or restricted dissemination or distribution.
-
Code, Cipher, and Cryptographic System: Includes their usual meanings as well as any method of secret writing and any mechanical or electrical device or method used to disguise or conceal the contents, significance, or meanings of communications.
-
Communication Intelligence: All procedures and methods used in the interception of communications and the obtaining of information from such communications.
-
Unauthorized Person: Any person who does not possess proper security clearance or authorization to access or receive the specific classified information.
What Must Federal Prosecutors Prove to Convict Under 18 U.S.C. § 798?
To secure a guilty verdict under 18 U.S.C. § 798, the United States Department of Justice must prove the following legal elements beyond a reasonable doubt:
-
Classified Status: The information in question was officially designated as classified information by a U.S. government agency at the exact time of the alleged disclosure.
-
Covered Subject Matter: The information pertained directly to codes, ciphers, cryptographic systems, cryptographic devices, communications intelligence activities, or foreign communications intelligence.
-
Unauthorized Disclosure or Misuse: The defendant communicated, furnished, transmitted, published, made available, or used the classified material to an unauthorized person or in a manner prejudicial to U.S. interests or beneficial to a foreign government.
-
Knowledge and Willfulness: The defendant acted knowingly (aware of the classified status) and willfully (with deliberate intent to break the law or breach non-disclosure duties). Accidental loss or simple negligence does not meet the criminal standard under 18 U.S.C. § 798.
What Are the Penalties for Conviction Under 18 U.S.C. § 798?
A conviction for disclosing classified information carries severe statutory penalties under federal sentencing guidelines.
|
Penalty Type |
Statutory Maximum & Legal Consequences |
| Federal Prison Term | Up to 10 years in federal prison per count |
| Monetary Fines | Fines up to $250,000 for individuals (or higher depending on statutory enhancements) |
| Asset Forfeiture | Mandatory forfeiture of any financial proceeds, payments, or assets derived from the crime, as well as equipment used to facilitate the disclosure |
| Collateral Consequences | Immediate revocation of security clearances, permanent loss of public trust positions, dishonorable discharge (if military), and a permanent federal felony record |
Hypothetical Examples of 18 U.S.C. § 798
Example 1: Willful Disclosure (Guilty of 18 U.S.C. § 798)
An intelligence analyst holding top-secret clearance knowingly sells technical manuals detailing U.S. military cryptographic systems to a representative of a foreign government for monetary compensation. Because the analyst knowingly and willfully disclosed classified cryptographic information, they are subject to prosecution under 18 U.S.C. § 798.
Example 2: Negligent Misplacement (Not Guilty of 18 U.S.C. § 798)
A communications officer inadvertently leaves a classified folder containing code keys on a table in a public cafe, but realizes the error and retrieves it minutes later. While the officer faced administrative sanctions, security clearance revocation, and potential prosecution under other negligence-based defense statutes (such as 18 U.S.C. § 793(f)), they cannot be convicted under 18 U.S.C. § 798 because there was no willful intent to disclose or transmit classified material.

What Are the Defense Strategies Against 18 U.S.C. § 798 Charges?
Federal defense attorneys employ several legal strategies to defend against national security charges under 18 U.S.C. § 798:
-
Lack of Willful Intent: Demonstrating that the disclosure was inadvertent, accidental, or made without criminal intent undermines the prosecution's burden of proving willfulness.
-
Information Was Unclassified or Declassified: Presenting evidence that the material was not officially classified at the time of disclosure or had already been formally declassified by proper executive authority.
-
Good-Faith Authorization: Showing that the defendant reasonably believed they had proper authorization or were directed by a superior official with proper authority to release the information.
-
Statutory Whistleblower Protections: Establishing that the communication met specific legal standards under federal Whistleblower Protection acts when exposing government wrongdoing to authorized legislative oversight bodies.
Frequently Asked Questions (FAQs)
What is the primary difference between 18 U.S.C. § 793 and 18 U.S.C. § 798?
While 18 U.S.C. § 793 broadly covers all national defense information (NDI), 18 U.S.C. § 798 specifically targets classified cryptographic systems, ciphers, codes, and communications intelligence activities. Section 798 also specifically requires that the information was formally designated as classified at the time of disclosure.
Does 18 U.S.C. § 798 apply to media members or journalists who publish classified information?
Yes. The statutory language of 18 U.S.C. § 798 explicitly criminalizes anyone who "publishes" covered classified cryptographic or communication intelligence information without authorization, making publishers and news organizations potentially subject to federal prosecution.
Can an individual be charged under 18 U.S.C. § 798 if no financial payment was received?
Yes. Receiving monetary compensation or personal benefit is not a required element of 18 U.S.C. § 798. Merely communicating, transmitting, or making classified cryptographic or intelligence data available to an unauthorized person satisfies the statute.
What constitutes an "unauthorized person" under federal law?
An unauthorized person is anyone who lacks a valid security clearance at the required level, an official "need-to-know," or explicit government clearance to access the specific classified intelligence material.
Can accidental disclosure lead to a conviction under 18 U.S.C. § 798?
No. Section 798 requires the government to prove that the defendant acted "knowingly and willfully." Purely accidental disclosures or simple mistakes do not meet this specific intent requirement, though they may trigger security clearance revocation or administrative penalties.
Does declassifying a document after disclosure eliminate criminal liability?
No. The statute explicitly measures the status of the information "at the time of a violation." Subsequent declassification by the government does not retroactively erase a crime committed when the information was classified.
