Several news sources are reporting on efforts by the U.S. Department of Defense to find Julian Assange, a founder of WikiLeaks. I reported here last week about the government’s detention of Army Specialist Bradley Manning (and how Manning could have blown the whistle with legal protections). Phil Shenon writes in The Daily Beast that the government is concerned that Manning may have given WikiLeaks.org 260,000 classified State Department cables relating to the wars in Afghanistan and Iraq. Shenon quotes an unnamed U.S. official saying, "We’d like to know where he is; we’d like his cooperation in this." Assange canceled an appearance in Las Vegas for the Investigative Reporters and Editors’ conference citing unspecified security concerns. Daniel Ellsberg told The Daily Beast that, "Assange is in some danger." WikiLeaks has previously reported that it relies on a panel of confidential experts to assess the authenticity and public interest in releasing documents submitted to them. I can imagine that it might take them some time to review 260,000 documents that could become the Pentagon Papers of this millennium’s new wars.
