HARRISBURG, Pa. — A handcuffed Jerry Sandusky testified by video link for nearly three hours Tuesday about his Penn State retirement deal and ties between the university and the youth charity he founded, as a hearing began to determine if he should get retirement benefits canceled over his child molestation conviction.

Speaking from the western Pennsylvania prison where he is serving a 30- to 60-year sentence, Sandusky described how he retired from Penn State in mid-1999 to take advantage of an early retirement incentive, and then was immediately rehired on a temporary basis to coach one last season.
