http://en.wikipedia.org/wiki/Business_PlotThe Business Plot, The Plot Against FDR, or The White House Putsch, was a conspiracy involving several wealthy businessmen to overthrow President Franklin D. Roosevelt in 1933.
Purported details of the matter came to light when retired Marine Corps General Smedley Butler testified before a Congressional committee that a group of men had attempted to recruit him to serve as the leader of a plot and to assume and wield power once the coup was successful. Butler testified before the McCormack-Dickstein Committee in 1934 <1>. In his testimony, Butler claimed that a group of several men had approached him as part of a plot to overthrow Roosevelt in a military coup. One of the alleged plotters, Gerald MacGuire, vehemently denied any such plot. In their final report, the Congressional committee supported Butler's allegations on the existence of the plot, <2> but no prosecutions or further investigations followed, and the matter was mostly forgotten.
