Judge James Zagel delivered that message to Blagojevich's lawyers during a status hearing Monday.
Zagel suggested they consider his warning a "red flag."
Prosecutors are not happy with Blagojevich's recent accusations that they have tried to hide evidence in the case.
On WLS Radio Tuesday morning, Blagojevich said prosecutors need to play all the secretly recorded conversations, so jurors can get the full context of what was said.
"There was n crime spree," Blagojevich said. "There were no crimes. Honest discussion. They say I said 'f'n'' golden.' You should see the context of which I say 'f'n'' golden' and what I meant. OK? I wanted to do stuff and get good results for people. That was part of the big, broad concept. And yeah, we talked about a whole bunch of ideas but always predicated on whether it was legal or not."
Blagojevich says he hopes to testify in his own defense at his retrial but that a decision would only be made during the trial.
