Keyser "was released on $500,000 bond on a charge of lying about [a] trip to Taiwan on an official government document."

Donald Keyser pleaded guilty on 12 December 2005 "to mishandling classified documents and lying about his relationship with a Taiwanese intelligence officer." He is scheduled for sentencing in February 2006. According to a plea agreement, Keyser had a personal relationship between 2002 and 2004 with "Isabelle Cheng, an employee of [Taiwan's] espionage agency, the National Intelligence Bureau."

This article furnishes a quick walkthrough of the Keyser case. Lefebvre's conclusion is that "Keyser seems to have been a target of opportunity who presented himself vulnerably due to his infatuation with Cheng. Or did Isabelle Cheng purposefully target him after spotting his fondness for her?"
