U.S. news reports say the former vice chairman of the Joint Chiefs of Staff is under investigation by the Justice Department for allegedly leaking classified information about a covert cyberattack on Iran's nuclear facilities.
NBC News and "The Washington Post" said retired Marine General James Cartwright has been told he is a target of the probe.
Cartwright was vice chairman of the Joint Chiefs -- or America’s second-highest ranking military officer -- from 2007 to 2011.
The probe is reportedly in connection with a "New York Times" article from June 2012 about the Stuxnet virus attack on Iranian nuclear facilities in 2010.
The report said President Barack Obama had decided to intensify cyberattacks, including the Stuxnet attack that temporarily disabled centrifuges Iran was using to enrich uranium.
