Chicago Rep. Jesse Jackson Jr., D-Ill., is the anonymous "Senate Candidate No. 5" whose emissaries Illinois Gov. Rod Blagojevich reportedly offered up to $1 million to name him to the U.S. Senate, his attorney confirmed today after it was reported earlier on ABCNews.com "The Blotter".

According to the FBI affidavit in the case, Blagojevich "stated he might be able to cut a deal with Senate Candidate 5 that provided Rod Blagojevich" with something "tangible up front."

Jackson told ABC News this morning he was contacted Tuesday by federal prosecutors in Chicago whom he said "asked me to come in and share with them my insights and thoughts about the selection process."

Jackson Jr.'s attorney James Montgomery confirmed that the Chicago congressman is "Senate Candidate #5" but said "Jackson has never authorized anyone to seek the Governor's support in return of money, fundraising or other things of value."
