Reuben Moon reported on the US House of Representatives version of the bill, HR 26656, in January 1911. His stated purpose for bringing the bill forward were several cases of Espionage that went unprosecuted because the United States, unlike other countries at the time, lacked any anti-Espionage law. He gave examples from the Panama Canal, the Philippines, and elsewhere, in which sketches or blueprints of military installations had been available to foreign parties, sometimes for money. He also cited recent wars, like the
Russo-Japanese War, where he argued knowledge of the enemy had been decisive. The act was entitled "An Act to prevent the disclosure of national defense secrets". It was approved on March 3, 1911. At the time, the United States, under general
John J. Pershing, and President
William Howard Taft, was fighting the
Moro Rebellion in the southern
Philippines, a fallout from the
Spanish–American War of 10 years earlier. The law specifically mentioned the Philippines. The language of the 1911 act, especially the notion of information 'relating' to the 'national defense' being obtained or delivered to 'those not entitled to receive it', was retained through subsequent American secrecy laws, including the
Espionage Act of 1917 and the
McCarran Internal Security Act of 1950. Many later Espionage Act cases, for example
Gorin v. United States, involved arguments about the exact meaning of terms like 'national defense'. == Brief history of US government secrecy ==
