Final answer:
Father Charles Coughlin blamed the "Jewish-controlled" banks on his radio broadcasts for the economic crisis, contributing to his anti-Semitic rhetoric.
Step-by-step explanation:
On his weekly radio broadcasts, Father Charles Coughlin blamed the "Jewish-controlled" banks for the economic crisis. Coughlin, known for his vehemently anti-Semitic and incendiary rhetoric, accused a supposed Jewish syndicate of influencing economic policies and causing financial turmoil for the United States. His denunciation of international bankers as enemies of America and his conspiratorial outlook contributed to his initial support, which waned as his remarks became more extreme and offensive.
