A few days later, Stuckey invited Oswald to take part in a radio debate with Bringuier and Edward Butler, executive director of the anti-Communist group Information Council of the Americas (INCA). The debate took place on August 21; both Stuckey and Edward Scannell Butler 3rd had in the meantime discovered the story of Oswald's 1959 defection to the Soviet Union and confronted him with it. During the debate, Bringuier challenged Oswald to agree with Fidel Castro's denunciation of President Kennedy as a ruffian and a thief.
