President Barack Obama asked the Department of Defense last June to carry out a cyber attack.
The revelation was made by a non-profit organization Federation of American Scientists (FAS).
According to the Mashable, the U.S. Air Force declassified a 15-page policy directive, containing a single sentence that is enough to prove Obama ordered the military to carry out an aggressive operation in cyberspace.
FAS said that text is full of jargon, but reveals two important details. First is the word 'offensive'. This means whatever the U.S. was doing during this operation, it involved more than defending the country from cyberattacks, the report said.
The second is the phrase 'execute order'. According to the Department of Defense, an execute order is 'an order issued by the chairman of the joint chiefs of staff, at the direction of the secretary of defense, to implement a decision by the president to initiate military operations,' it added.
The chairman of the joint chiefs of staff is America's highest-ranking military officer, meaning the president asked the Pentagon to carry out an online 'military operation,' the report added.
