Suburban mayors back Jackson for Senate

They said Jackson, the man who represents their communities in the U.S. House of Representatives, should represent the entire state in the U.S. Senate.

President-elect Barack Obama will resign officially Sunday as an Illinois senator so that he can focus on his transition process to the White House.

Illinois Gov. Rod Blagojevich will choose Obama's successor in the Senate. There has been no indication yet of when he will make that decision.
