Judge in Rod Blagojevich case denies Rob Blagojevich a separate trial
Earlier, Zagel turned down a request from Blagojevich's brother, businessman Robert Blagojevich, to be tried separately.
Robert Blagojevich's lawyer, Michael E. Ettinger, had argued that the evidence against the former governor could "spill over" and bias jurors against his client.
But Zagel said it was more likely that focusing the blame on the former governor and not his brother would actually work to the advantage of Robert Blagojevich.
Rod Blagojevich is charged with scheming to use his power as governor to fill a vacant U.S. Senate seat by selling or trading President Obama's former seat and illegally pressuring potential donors for campaign contributions. His brother has been charged with helping him.
Both men have pleaded not guilty and denied wrongdoing. The trial is scheduled to start June 3.
