The Espionage Act Revival: Classification as Political Weapon

Opening Thesis

The Espionage Act of 1917, written to prosecute German spies during the First World War, has become the preferred instrument for prosecuting unauthorized disclosures of classified information by government officials and journalists' sources. Its revival as a political tool is not new — the Obama administration used it more than all previous administrations combined — but its current application has achieved a scope that would have startled its authors.

What Happened

THE HISTORICAL ECHO

The Espionage Act was written for a specific purpose: to prevent the transmission of defense information to foreign governments during wartime. Its text, however, is broad enough to criminalize any unauthorized disclosure of information "relating to the national defense." This breadth was not an oversight. It was a feature of wartime legislation drafted in an atmosphere of genuine fear about German sabotage networks operating on American soil.

The Act was used sparingly for most of the 20th century. Prior to 2009, only three government employees had been prosecuted under its provisions for leaking to the press. Since 2009, eleven have been charged. The acceleration is bipartisan: three prosecutions under Obama, four under Trump (first term), two under Biden, and five under Trump (second term). The pattern transcends partisan preference because the institutional incentive — executive branch control over information — transcends partisan identity.

THE INSTITUTIONAL CONTINUITY

The classification system is the mechanism that makes the Espionage Act a political weapon. There are approximately 1.3 million people with Top Secret clearances and over 4 million with some level of classified access. The amount of information classified annually exceeds 50 million decisions. The system is so vast that oversight is structurally impossible — no individual, committee, or agency can review more than a fraction of classification decisions in any given year.

This means the executive branch has unilateral, largely unreviewable authority to determine what information is secret. Combined with the Espionage Act's criminalization of unauthorized disclosure, this creates a system in which the government can conduct activities in secret, classify evidence of those activities, and prosecute anyone who reveals them — including evidence of illegality.

THE MYTH BEING SOLD

The government argues that prosecutions protect national security by deterring unauthorized disclosures that could endanger sources and methods. This is sometimes true. It is also true that every surveillance program later found to be illegal or unconstitutional was revealed through unauthorized disclosure. The NSA's warrantless wiretapping program (2005), the PRISM program (2013), and the current program at issue were all classified, all revealed by leakers, and all subsequently found to exceed legal authority.

WHAT THIS ACTUALLY CHANGES

The prosecution creates a precedent that disclosing evidence of potentially illegal government surveillance is a criminal act regardless of the surveillance's legality. This is the logical endpoint of a system that allows the executor of a program to determine whether evidence of that program's illegality may be disclosed.
