CHICAGO- A lawyer for U.S. Rep. Jesse Jackson Jr. says the congressman is the “Senate Candidate 5” mentioned in the federal corruption complaint against Illinois Gov. Rod Blagojevich.

Attorney James D. Montgomery Sr. said Wednesday that Jackson never had a “pay-to-play” conversation with Blagojevich.

The governor is accused of trying to profit from his authority to appoint a replacement to fill President-elect Barack Obama’s Senate seat.

Montgomery says Jackson “never authorized anyone to seek the governor’s support” for anything of value.

And he says Jackson isn’t aware of any associates having made such an overture on his behalf.

Montgomery says Jackson learned he was mentioned in the complaint against Blagojevich the night before the governor’s arrest on Tuesday.

Jackson is expected to give a press conference on the allegations shortly.
