ABC News host Jonathan Karl clashed with political strategist and convicted criminal Steve Bannon about violence from Republicans. During an interview that aired Sunday on ABC's This Week program, Bannon dismissed death threats received by Dr. Anthony Fauci after he called to put the doctor's head "on a pike." "I'm not backing off my rhetoric," Bannon insisted. "Are you concerned about those death threats, though?" Karl asked. "Do you think I don't get death threats and have security all the time?" Bannon retorted.
