Rezko may be cooperating with feds

CHICAGO, Aug. 28 (UPI) -- Tony Rezko, a Chicago developer and one time fundraiser for Barack Obama, may be being pressured by federal investigators to tell on Illinois politicians.

Rezko has been jailed since June while awaiting sentencing in October on mail and wire fraud, aiding and abetting bribery and money laundering convictions. He faces two more trials.

The Chicago Sun-Times said Thursday that sources said Rezko has been seen a dozen times at the Chicago federal courthouse and, one source said, has been twice in the office of the U.S. attorney. This has raised speculation he is cooperating in "Operation Board Games," an ongoing probe into state corruption that allegedly may reach all the way to Democratic Gov. Rod Blagojevich.

Rezko's work as an adviser and fundraiser for Blagojevich may be of special interest to federal authorities, sources told the Sun-Times.

Rezko lawyer Joseph Duffy called the idea of his client's involvement in other prosecutions "bogus." He noted that his lawyers have permission to meet with him at the courthouse, the Sun-Times said.
