The DailyBeast website reports Pentagon investigators have begun searching for Julian Assange, the founder of the whistleblowing website Wikileaks. Earlier this week it was revealed the website might be in possession of hundreds of thousands of classified State Department cables. Wikileaks made international headlines in April when it released a classified US military video showing a US helicopter gunship indiscriminately firing on Iraqi civilians, killing twelve people, including two employees of the Reuters news agency. The US military recently arrested Army Specialist Bradley Manning, who may have been responsible for leaking the classified video. Manning has claimed he sent Wikileaks the video along with 260,000 classified US government records. Manning, who was based in Iraq, reportedly had special access to cables prepared by diplomats and State Department officials throughout the Middle East.
