One of the main witnesses in Julian Assange’s extradition case has admitted he made false claims against Assange in exchange for immunity from prosecution, a bombshell revelation that could have a major impact on the WikiLeaks founder’s fate. Assange faces up to 175 years in prison if brought to the U.S., where he was indicted for violations of the Espionage Act related to the publication of classified documents exposing U.S. war crimes. According to a new article in the Icelandic newspaper Stundin, the convicted hacker Sigurdur “Siggi” Thordarson falsely claimed he was a prominent WikiLeaks representative instructed by Assange to carry out hacking attacks, but he was in fact only tangentially involved with the organization. The article suggests the U.S. Justice Department collaborated with Thordarson to generate the indictment for Assange that was submitted to the British courts. “This is just the latest revelation to demonstrate why the U.S. case should be dropped,” says Jennifer Robinson, a human rights attorney who has been advising Assange and WikiLeaks since 2010. “The factual basis for this case has completely fallen apart.”
