1933 : The Business Plot
In 1934, Butler came forward and reported to the U.S. Congress that a group of wealthy pro-Fascist industrialists had been plotting to overthrow the government of President Franklin D. Roosevelt in a military coup. Even though the McCormack-Dickstein Committee (precursor to the House Un-American Activities Committee) corroborated most of the specifics of his testimony, no further action was taken.
In his testimony, Butler claimed that a group of 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 of the existence of the plot, but no prosecutions or further investigations followed, and the matter was mostly forgotten.
