The Service Employees International Union was named in the litany of corruption charges outlined a criminal complaint against Illinois Gov. Rod Blagojevich.

The complaint said Blagojevich was seeking a position paying upward of $250,000 in exchange for considering naming Valerie Jarrett to fill President-elect Barack Obama's U.S. Senate seat, The New York Times said. Jarrett was Obama's first choice as his successor.

Among the charges a federal investigation leveled against Blagojevich is an accusation that he was trying to sell Obama's seat to the highest bidder. The governor was arrested Tuesday.

The Illinois branch of SEIU in a statement said, "We have no reason to believe that SEIU or any SEIU official was involved in any misconduct." The union said it was cooperating with federal investigators.

Union leaders said the criminal complaint didn't accuse the unnamed official of wrongdoing.
