Mr. Obama has said no representatives of his had anything to do with alleged deals for the Senate seat, according to the motion. Mr. Blagojevich argues those statements "contradict the testimony of an important government witness."
The filing said the witness was a union representative, without naming the person. Mr. Obama is "the only one who can say if emissaries were sent on his behalf, who those emissaries were, and what, if anything, those emissaries were instructed to do on his behalf," the motion said.
The alleged contradictory information was redacted in Thursday's filing.
