Tony Rezko will not learn how much time he must serve behind bars until later this year. The former political fundraiser might be called to testify in the upcoming re-trial of former Illinois Governor Rod Blagojevich.

Rezko had been in solitary confinement in federal jail since he was convicted of fraud and pay-to-play schemes within the Illinois government two and a half years ago. But he was recently moved out of solitary to a county facility with other inmates.

A clean-shaven, but thin Rezko appeared in front of Judge Amy St. Eve. He complained of a lack of fresh air and contact with his family, but Rezko also said he wants to push his sentencing date back even further until after Rod Blagojevich’s re-trial.

Rezko’s attorney told reporters after the court hearing that Rezko may be called as a witness at Blagojevich’s next trial, but a spokesman for the prosecutors standing nearby cut in to say there’s no word on whether Rezko will be a witness. Prosecutors surprisingly did not call Rezko at Blagojevich’s first trial that ended with a hung jury on most counts.
