What Is the Espionage Act
The Espionage Act is a United States federal law enacted in 1917 during World War I.

The law remains in force and has been amended several times since its original passage.
Key Provisions and Scope
The act makes it a crime to knowingly transmit or attempt to transmit national defense information to unauthorized persons or foreign entities. It also prohibits unauthorized gathering or delivery of defense information and covers actions such as spying, sabotage, and interference with military operations. Penalties can include heavy fines and lengthy prison sentences.
Historical Context and Modern Relevance
Originally intended to suppress dissent and secure wartime communications, the Espionage Act has been used in high-profile cases involving leaks of classified material. It continues to shape debates over press freedom, whistleblowing, and government secrecy.
