At the center of the investigations is Jesse Jackson Junior.
Former Governor Blagojevich's brother, Rob, spoke out today about Congressman Jackson.
Rob Blagojevich says at least two people from Jackson's staff contacted him about giving campaign money for the seat.
Jesse Jackson Junior says that is not what happened. "Ethically and with honor. With dignity and the highest possible standards. So you did not ask someone to organize and raise a lot of money? I have made that perfectly clear."
Jackson says he is confident he will be vindicated when the investigation is complete.
