The “Espionage Act” is a common name for several federal laws, not one rule that makes every disclosure of a classified document a crime. In leak cases, the main provisions discussed are 18 U.S.C. §§ 793, 794 and 798. They cover different information, conduct, recipients and mental states; whether a particular disclosure violates one depends on the statute’s elements and the facts.
What does “the Espionage Act” mean?
The label usually refers to provisions in Chapter 37 of Title 18 of the U.S. Code. The provisions most relevant to leaks do not all define espionage in the everyday sense of secretly helping a foreign power. Section 793 addresses specified conduct involving information relating to the national defense; § 794 focuses on transmission to foreign-government recipients with a specified harmful intent or belief; and § 798 covers particular kinds of classified information, including codes and communications intelligence.

Those distinctions matter because “classified” is not a substitute for proving a statute’s elements. Section 793 uses the phrase “information relating to the national defense,” and its application depends on the statutory text and evidence in a particular case—not simply on whether a document carries a classification marking or has been described as a leak.

How do §§ 793, 794 and 798 differ?
| Provision | Information covered | Conduct and recipient focus | What distinguishes it |
|---|---|---|---|
| 18 U.S.C. § 793 | Information relating to the national defense | Depending on the subsection, gathering information with specified intent, communicating or delivering it to someone not entitled to receive it, or willfully retaining it and failing to deliver it to the proper government officer or employee | It covers several forms of conduct; the elements and mental-state language differ by subsection. |
| 18 U.S.C. § 794(a) | Information relating to the national defense | Communicating, delivering or transmitting it to a foreign government or specified foreign recipients | The provision includes intent or reason to believe the information will be used to injure the United States or advantage a foreign nation. |
| 18 U.S.C. § 798 | Defined categories of classified information, including information concerning codes, cryptographic systems and communications intelligence | Knowing and willful communication, furnishing, transmission, publication or other availability to an unauthorized person | Its subject matter is limited by the statute; it is not a general prohibition covering every classified disclosure. |
The table is a high-level orientation, not a replacement for the full statutory language. A case turns on the particular subsection charged and whether the evidence supports each required element.

When can § 793 apply to a leak?
Section 793 is titled “Gathering, transmitting or losing defense information.” Its subsections describe distinct conduct. Some address obtaining national-defense information with specified intent; others address communicating or delivering it to a person not entitled to receive it. Another addresses willful retention and failure to deliver the information to the proper government officer or employee. The Department of Justice’s Criminal Resource Manual summarizes the section as covering gathering, unauthorized transmission or loss of national-defense information, as well as conspiracies.
That summary should not be read as saying every unauthorized disclosure necessarily violates § 793. The government would have to proceed under a particular subsection and establish its elements. The statute’s national-defense-information framework, the nature of the conduct, the recipient, and the applicable mental-state requirement all matter.
Is leaking classified information always espionage under § 794?
No. Section 794(a) is narrower in an important respect: it concerns transmission of national-defense information to a foreign government or specified foreign recipients, together with intent or reason to believe the information will be used to injure the United States or advantage a foreign nation. A disclosure to an unauthorized person is not, by that fact alone, the same as conduct satisfying those recipient and intent-or-belief terms.

Why is § 798 different?
Section 798 concerns certain classified information about codes, cryptographic systems and communications intelligence. It reaches specified knowing and willful acts of communicating, furnishing, transmitting, publishing or otherwise making that information available to an unauthorized person. Its defined subject matter separates it from provisions framed around national-defense information more broadly.
For that reason, § 798 should not be described as a catch-all law for any public disclosure of classified material. Whether it applies depends in part on whether the information falls within the categories the statute covers, as well as on the conduct and other statutory requirements.

Does the Pentagon Papers decision protect publishers or sources?
In New York Times Co. v. United States (1971), commonly called the Pentagon Papers case, the Supreme Court rejected the government’s attempt to prevent the New York Times and Washington Post from publishing a classified study. The decision addressed that effort to impose a prior restraint; it did not resolve every question about criminal liability for a source who obtains or transmits information, or for a publisher after publication.

A government attempt to block publication in advance is not the same as prosecuting a source for obtaining or transmitting material, or prosecuting a publisher after publication. The 1971 ruling should therefore not be treated as a blanket immunity for every person involved in a classified disclosure.

Are there authorized channels for classified whistleblower disclosures?
Some intelligence whistleblower statutes provide prescribed channels for reporting classified information, including disclosure to the Intelligence Community Inspector General under applicable security standards and procedures. Such a channel is a formal oversight route, not permission to release the information publicly.
“Whistleblower” is not, by itself, a blanket exemption from rules governing classified information. Protections and procedures depend on the applicable statute and process; describing a public disclosure as whistleblowing does not establish that it followed an authorized channel. A 1998 Department of Justice Office of Legal Counsel opinion discussed the constitutional treatment of proposed congressional disclosure channels for classified intelligence information, but it is historical background rather than a comprehensive guide to current procedures.
What role does CIPA play in a prosecution?
The Classified Information Procedures Act (CIPA), enacted in 1980, sets procedures for handling classified information in criminal cases. It can matter when classified evidence is implicated in a prosecution. CIPA does not itself create the substantive offenses in the Espionage Act provisions, and it does not independently determine whether a disclosure was illegal.

What determines whether a particular leak is unlawful?
The answer depends on the specific provision and subsection under consideration, the information involved, what the person did, to whom it was communicated, and the mental state the statute requires. Classification status may be relevant, but it does not by itself answer whether § 793, § 794 or § 798 has been violated. The statutory text controls, and assessing a real person’s potential exposure requires a fact-specific legal analysis.
