A federal appeals court has turned down former Illinois Gov. Rod Blagojevich's latest request to delay his corruption trial.

The 7th U.S. Circuit Court of Appeals said Tuesday it has no jurisdiction to delay the trial set to get under way June 3.

Defense attorneys want the trial put on hold until the U.S. Supreme Court resolves challenges to a federal statute that forms the basis for a number of charges Blagojevich faces.

U.S. District Judge James B. Zagel had already twice refused to grant a delay.

Defense attorney Sam Adam has said he's prepared to go to the U.S. Supreme Court.

Blagojevich has pleaded not guilty to charges he schemed to use his power as governor to make appointments by selling or trading President Barack Obama's former U.S. Senate seat.
