Rev Charles Coughlin Father of Social Justice
https://en.wikipedia.org/wiki/Charles_Coughlin
The J. Edgar Hoover when Director of FBI aided and facilitated subversive and traitorous actions before during and after WW2.
Rev Coughlin preached anti-comunist pro nazi rhetoric out of his headquarters in Royal Oak Michigan starting in the late 30's. In addition to his sermons at local churches etc, he also published a magazine called Social Justice and did radio spots. The FBI files are full of examples of his absolutely anti-American rhetoric.
People started complaining about him to the FBI Director shortly after starting with Marine Gen Smedley Butler. Butler is famous for exposing The Business Plot of 1933. A powerful group of American Industrialists who were both financing and facilitating the NAzi war machine. (see MacCormack Dickstein Committee or The Committee of Un-American Activities)
Apparently Rev Coughlin had approached Gen Butler about leading un unknown army in Mexico of 260,000 men to do something. There was some talk about having arms suppiles here to supply them with. There was also some some implying of the removal of the sitting President of that time, but not by Coughlin. This was all known to Hoover as the reports of Coughlins activities come pouring in.
FBI Director ignores ALL requests for information or investigation from 1939 into the 70's They are approached for the records in the 60's and 70's for thesis and biography works. Still refused. FBI is accused of taking Coughlins private papers. They deny. Witnesses to Coughlins activities are paid more attention. Those they check out.
All agencies are refused any real records. Only surveillance reports of his sermons were sent to any requests from officials. Citizens ignored completely. USAG, State Dept, DNI.
There was talk of a secret grand jury indictment in DC, altho there was no documents related to that. There are also accusations of a deal between the Church and the FBI that there will be no prosecution of Coughlin as long as the Church reigns him in when necessary. Finally, dockworkers that had previously made a report to the FBI about Coughlins activities on the dock went to someone who took it to the DNI.
The FBIs version reports about propaganda handed out at the docks but the DNI gets the version where Coughlin meets a Nazi sub off the coast of Long Beach and off the Florida coast as well.
The FBI report did not include this and so The FBI director was forced to launch some investigation. This was before and during the War.
