Several onetime allies of for- mer Gov. Rod Blagojevich have already lined up as government witnesses against him, and another close friend and confidant could be next.
Sources familiar with the case said Christopher Kelly has had preliminary discussions with prosecutors about possibly cooperating, but he has not yet agreed to do so.
As Kelly weighs his future, his lawyers asked a federal judge Tuesday to delay his sentencing until October. Kelly, 50, a wealthy roofing company owner, pleaded guilty in January to tax-fraud charges for concealing his use of corporate funds to cover gambling debts. U.S. District Judge Elaine Bucklo is considering the request.
