On Wednesday, September 13, 2000, Wen Ho Lee was released from federal prison. He pleaded guilty to one of the fifty-nine counts charged against him, the rest of which were dropped by federal prosecutors. The single charge (using an unsecure computer to download a document relating to national defense onto a tape) was punished by a sentence of nine months in solitary confinement, time served.
The judge's comments are available here.
As part of the deal, he signed an oath stating he never intended to harm the United States and never passed the secrets he copied to any third party.
