Sandusky was quiet in court during this phase early Wednesday, leafing through a binder with plastic-covered pages and pausing at times when Cleland commented from the bench.
More than 600 jury duty summonses were sent out to residents in Centre County, the home of Penn State University’s main campus.
All the jurors will have to say under oath they can be impartial.
Besides Sandusky family members, other names on the defense’s potential witness list include the widow and son of Joe Paterno, the late Hall of Fame football coach who was dismissed by university trustees in the aftermath of Sandusky’s arrest.
Assistant coach Mike McQueary and his father are also on the defense witness list.
Mike McQueary, on leave from the team, has said he saw Sandusky naked in a team shower with a young boy more than a decade ago and reported it to Paterno. Mike McQueary is also on the prosecution’s list, along with young men who have accused Sandusky of abusing them.
