In 1933, Retired Marine Corps Major General Smedley Butler was approached by wealthy industrialists and bankers who were plotting to create a fascist veterans' organization called the "American Liberty League" and use it in a coup d'état to overthrow United States President Franklin D. Roosevelt, with Butler as leader of that organization. In 1934 Butler testified to the McCormack--Dickstein Congressional committee on these claims. In the opinion of the committee, these allegations were credible. One of the purported plotters, Gerald MacGuire, vehemently denied any such plot. In their report, the Congressional committee stated that it was able to confirm Butler's statements other than the proposal from MacGuire which it considered more or less confirmed by MacGuire's European reports. No one was prosecuted.
Marine Corps Maj.-Gen. Smedley Butler was approached by a wealthy and secretive group of industrialists and bankers, including Prescott Bush the current President's grandfather, who asked him to command a 500,000 strong rogue army of veterans that would help stage a coup to topple then President Franklin Delano Roosevelt.
