A retired American four-star general is under investigation for allegedly leaking highly classified data to the New York Times.
Various news outlets say James "Hoss" Cartwright disclosed details of the Stuxnet computer worm.
The malware computer program was found in 2010 to have targeted Iran's nuclear facilities, while the United States and Israel have been accused of its development.
North America correspondent John Stempin explains to Kerri Worthington what's led to the investigation.
