(CNN) - According to prosecutors, Illinois Gov. Rod Blagojevich knew all too well how much leverage he had as the only person who could appoint Barack Obama's Senate replacement.
A criminal complaint released Tuesday details conversations Blagojevich is said to have had with potential Senate candidates, who are identified only by a number.
Blagojevich is said to have called the open seat a "f-ing valuable thing" and something you don't give away "for nothing."
No one mentioned as a possibility for the seat is saying that he or she is one of those unnamed candidates in the complaint.
