U.S. military officials [have said] that investigators have been unable to make any direct connection between a jailed army private suspected with leaking secret documents and Julian Assange, founder of the whistleblowing website WikiLeaks. The officials say that ... there is apparently no evidence he passed the files directly to Assange, or had any direct contact with the controversial WikiLeaks figure. WikiLeaks' release of secret diplomatic cables last year caused a diplomatic stir and laid bare some of the most sensitive U.S. dealings with governments around the world. It also prompted an American effort to stifle WikiLeaks by pressuring financial institutions to cut off the flow of money to the organization. U.S. Attorney General Eric holder has said his department is also considering whether it can prosecute the release of information under the Espionage Act. Assange told MSNBC TV last month that WikiLeaks was unsure Army PFC Bradley Manning is the source for the classified documents appearing on his site. "That's not how our technology works, that's not how our organization works," Assange said. "I never heard of the name of Bradley Manning before it appeared in the media." He called allegations that WikiLeaks had conspired with Manning "absolute nonsense." Anti-war groups, a psychologist group as well as filmmaker Michael Moore and Pentagon Papers whistleblower Daniel Ellsberg have called for Bradley to be released from detention.
