As his sentencing nears, pressure is mounting on Tony Rezko to cooperate with federal investigations into some of the highest-profile politicians in the state -- including Gov. Blagojevich.
Two more trials -- one in Chicago next spring, one in Las Vegas -- hover over the Wilmette businessman and onetime prolific political fund-raiser for the governor and Barack Obama.
Now, sources tell the Chicago Sun-Times that Rezko has been seen at the federal courthouse as many as a dozen times since his June conviction. He's been held since then at the Metropolitan Correctional Center in downtown Chicago.
