Stuxnet Leak Investigation Focuses on Former Vice Chairman of the Joint Chiefs of Staff

He apparently tried to bolster the president's reputation

Legal sources tell NBC News that the former second ranking officer in the U.S. military is now the target of a Justice Department investigation into a politically sensitive leak of classified information about a covert U.S. cyber attack on Iran's nuclear program.

According to legal sources, Retired Marine Gen. James "Hoss" Cartwright, the former vice chairman of the Joint Chiefs of Staff, has received a target letter informing him that he's under investigation for allegedly leaking information about a massive attack using a computer virus named Stuxnet on Iran's nuclear facilities. Gen. Cartwright, 63, becomes the latest individual targeted over alleged leaks by the Obama administration, which has already prosecuted or charged eight individuals under the Espionage Act.
