A federal judge in Chicago has refused to issue a subpoena for President Barack Obama to testify at former Illinois Gov. Rod Blagojevich's political corruption trial.
U.S. District Judge James Zagel ruled Friday that lawyers for Blagojevich had not produced sufficient evidence that Obama would have anything material to say on the witness stand.
Defense attorneys had claimed that the president could shed light on charges that Blagojevich schemed to sell or trade Obama's former U.S. Senate seat.
Blagojevich has pleaded not guilty to the charges. The trial is set to start June 3.
