CHICAGO - The Democratic National Committee has invited some high-ranking officials from Sen. Barack Obama's home state to speak at the party's convention in Denver next week - but not Gov. Rod Blagojevich. | Convention, Du Quoin State Fair on governor's schedule? | Vice president short-listers mix positives, negatives

Those invited include Treasurer Alexi Giannoulias, Comptroller Dan Hynes and Attorney General Lisa Madigan. All three are potential rivals of Blagojevich, should he run for re-election. Chicago Mayor Richard Daley has also been invited to speak.

Obama is the presumptive presidential nominee, and the final decision about who speaks at the convention rests with his campaign.

Blagojevich's administration has been dogged by a number of federal investigations. But neither the DNC or Obama's campaign is talking about the reason he wasn't asked to speak.
