Business Plot

The Business Plot was a political conspiracy in 1933 in the United States. Retired Marine Corps Major General Smedley Butler claimed that wealthy businessmen were plotting to create a fascist veterans' organization with Butler as its leader and use it in a coup d'état to overthrow President Franklin D. Roosevelt. In 1934, Butler testified before the United States House of Representatives Special Committee on Un-American Activities (the "McCormack-Dickstein Committee") on these claims. No one was prosecuted.

At the time of the incidents, news media dismissed the plot, with a New York Times editorial characterizing it as a "gigantic hoax". While historians have questioned whether or not a coup was actually close to execution, most agree that some sort of "wild scheme" was contemplated and discussed.

On July 17, 1932, thousands of World War I veterans converged on Washington, D.C., set up tent camps, and demanded immediate payment of bonuses due to them according to the World War Adjusted Compensation Act of 1924 (the original act made the bonuses initially due no earlier than 1925 and no later than 1945). Walter W. Waters, a former Army sergeant, led this "Bonus Army". The Bonus Army was encouraged by an appearance from retired Marine Corps Major General Smedley Butler; as a popular military figure of the time, Butler had some influence over the veterans. A few days after Butler's arrival, President Herbert Hoover ordered the marchers removed, and U.S. Army cavalry troops under the command of General Douglas MacArthur destroyed their camps.
