Attorneys have filed a motion requesting the "earliest possible" sentencing date for convicted political fixer Tony Rezko.
The motion filed Wednesday in federal court says Rezko has been in solitary confinement at Chicago's Metropolitan Correctional Center since June 4 and "can no longer agree to delay sentencing."
The motion was first reported late Wednesday on the Chicago Sun-Times' Web site.
A judge canceled Rezko's sentencing date in October.
Rezko's since been seen in U.S. Attorney Patrick J. Fitzgerald's office. There hasn't been official confirmation that he's cooperating with federal prosecutors, but both sides say they're in discussions that could affect sentencing.
Messages left late Wednesday for Rezko's attorney and a U.S. attorney's office spokesman weren't immediately returned.
