I was always of the belief that Father Coughlin’s supporters in NYC were concentrated in Yorkville, but after listening to Rachel Maddow’s podcast I became aware of the group that lived in Brooklyn and that many of them lived close to where I live now. I decided to map the addresses of where these guys lived in 1940 and shortly afterwards. From the transcript Rachel Maddow's podcast entitled "Ultra." Maddow: In January 1940, it really was front page news all across the country when the head of the FBI, J. Edgar Hoover, personally announced this round-up, the mass arrest of the Christian Front in New York. Radio Announcer: In New York, the alleged ringleaders of a fantastic Christian Front plot to overthrow the United States government by force are now behind federal bars. J. Edgar Hoover charges that they had plotted widespread terroristic activities, bombings, and antisemitic outbursts. Maddow: Seventeen members of the Christian Front in New York were arrested. The majority of those arrested were either actively serving in the New York National Guard or they’d served in other branches of the military. All of them were charged with sedition, with a plot to overthrow the U.S. government by force. This is from some of the newspaper coverage from that day: "A plot to overthrow the United States "The plot, [Hoover] said, was aimed against Jews generally and involved seizure of key government agencies such as Federal Reserve banks, post offices, and Public Utilities.” Hoover said, quote, "The government they proposed setting up, they referred to as a 'dictatorship similar to Hitler's."The local press affectionately nicknamed them “The Brooklyn Boys.” The local Catholic Church supported them loudly. Nobody who was Jewish was allowed to sit on the jury. There was a local Catholic priest who was advising the Christian Front, who had been leading rallies to support them, who was close to Coughlin. His first cousin was picked as the foreman of the jury." The end result was that they were amazingly acquitted.
