The Department of Defense is blocking online access to news reports about classified National Security Agency documents made public by Edward Snowden. The blackout affects all of the department's computers and is part of a department-wide directive.
"Any website that runs information that the Department of Defense still considers classified" is affected, Pentagon spokesman Lt. Col. Damien Pickart told U.S. News in a phone interview.
According to Pickart, news websites that re-report information first published by The Guardian or other primary sources are also affected.
"If that particular website runs an article that our filters determine has classified information... the particular content on that website will remain inaccessible," he said.
Pickart said the blackout affects "millions" of computers on "all Department of Defense networks and systems."
