Rod Blagojevich have said there was one hold out who kept them from convicting Blagojevich of one of the most serious allegations: that he tried to sell an appointment to the U.S. Senate seat once held by President Barack Obama. Sources tell CBS 2 News that the holdout juror is Jo Ann Chiakulas, a retired state employee. She used to work for the Illinois Department of Public Health, had been a director of teen counseling for the Chicago Urban League
