The anonymous senate candidate — known only as ‘Senate Candidate 5’ — who allegedly offered Illinois Governor Rod Blagojevich $500k for Barack Obama‘s senate seat has been outed as Chicago Congressman Jesse Jackson Jr, writes the Chicago Sun-Times.

The alleged deal was caught on a wiretap secretly planted by the feds.

“‘In a recorded conversation on October 31, 2008, Rod Blagojevich described an earlier approach by an associate of Senate Candidate Five as follows: ‘We were approached “pay to play.” That, you know, he’d raise me 500 grand. An emissary came. Then the other guy would raise a million, if I made him (Senate Candidate 5) a senator,’ the affidavit accompanying Blagojevich’s criminal complaint states.

“Speculation has circulated that Jackson is Senate Candidate 5 since the complaint was released Tuesday. Jackson, who has aggressively campaigned for the Senate seat, told ABC news that he has not ‘been informed’ by federal prosecutors that he is Senate Candidate 5.”
