"This tape demonstrates Matt's tremendous courage and strength as he begins to disclose that Jerry Sandusky sexually abused him when he was a child," they said. "Although the tape was released without Matt's knowledge or permission, it illustrates that he made the difficult decision to come forward and tell the painful truth to investigators despite extraordinary pressure to support his father."

The audiotape's leak was the main subject of a meeting hastily called Tuesday by trial Judge John Cleland and attended by prosecutors, defense attorneys and even the judge who has overseen the grand jury that's investigated the Sandusky case, a source with knowledge of the meeting told CNN National Correspondent Susan Candiotti.

No one at the meeting took responsibility for sharing the tape with the media, the source told CNN. Jerry Sandusky's defense team was asked to turn over its copy of the tape, but it will remain available to them.

Cleland ordered that any discovery turned over to the defense in the Sandusky case be sealed unless it was put into evidence at trial. He also said defense attorneys shall give a sworn statement within 10 days as to what materials they received and who they have given it to.

The judge is trying to protect the current investigation and the privacy of the victims and witnesses.

Neither prosecutors nor defense attorneys, who have vowed an appeal, would comment on Tuesday's meeting.

Matt Sandusky's grand jury testimony remains a secret. Amendola said months ago he was not concerned about what the man said before the grand jury.

Karl Rominger, another defense attorney, had a jailhouse visit with Jerry Sandusky on Monday.

"I'm innocent," said Jerry Sandusky, in answer to questions CNN's Candiotti asked of him through his lawyer. "I didn't do it," he said, according to Rominger.

Rominger says Sandusky was bothered he didn't get to testify. But Jerry Sandusky doesn't regret his decision, according to his lawyer.

Sandusky, who was allowed Monday to call his wife, Dottie, is not allowed visitors until a psychiatric examination is completed that also will determine whether he remains on suicide watch, according to Rominger.

"Some of the guards are friendly and will talk with him. Others don't talk to him at all," according to Rominger.

Sandusky is allowed out of the small cell -- which features a toilet, sink and bed -- once a day to take a shower.

"He's come up with exercises to keep active," his lawyer told CNN. "Enough to work up a sweat."
