Blagojevich defense lawyer Sam Adam Jr. has begun questioning Ata. Things got off to a rocky start when Adam began asking him about how the FBI interviewed Ata after the Sept. 11, 2001, terrorist attacks.
Ata detailed that story in his 2008 testimony in the Rezko trial, saying the FBI found nothing wrong with him.
It was unclear why Adam was bringing it up now, and Judge James Zagel briefly sent the jurors out of the room to discuss it with Adam.
"The questioning is very repetitive," Zagel said. "He's told you what he thought. He's told the government what he thought
"I'm barring this line of questioning. Usually, if I sustain an objection, that means you don't repeat the question."
