The US Department of Justice has prepared additional charges against WikiLeaks founder Julian Assange based on testimony by a convicted conman Sigurdur Thordarson, a WikiLeaks press release published on Twitter says.
"The star witness in the pending new DoJ indictment […] is convicted fraudster and FBI informant Sigurdur Thordarson", WikiLeaks says.
Last week Thordarson was flown to the US where he was "comprehensively interrogated" by US officials, the press release says citing Dutch public broadcaster NOS.
Earlier in May, FBI Special Agent Megan Brown, who is leading the investigation against Assange, and prosecutor Kellen Dwyer reportedly, flew to Iceland to speak with Thordarson with the help of Icelandic police.
"The Trump administration is so desperate to build its case against […] Assange that it is using a diagnosed sociopath, a convicted conman and sex criminal, who was exposed by the highest levels of the Icelandic government as an FBI informant and who was involved in an entrapment operation in 2011 against Julian Assange", WikiLeaks editor-in-chief Kristinn Hrafnsson says.
"Thordarson stole tens of thousands of dollars from WikiLeaks, and impersonated Julian Assange in order to carry out the embezzlement", the document says.
The man underwent a psychiatric examination as a part of criminal prosecution, and was diagnosed as a sociopath, WikiLeaks said.
WikiLeaks claims that Washington's reliance on such unreliable sources as Thordarson and his fellow FBI informant Hector Monsegur could destroy the case inside the US. However, the US has an option to conceal the names of its sources in the extradition request making it impossible for Assange to challenge the credibility of the witnesses, the document says.
Hrafnsson sent a formal letter to a number of high-ranking Icelandic officials, including the prime minister, foreign minister, and general prosecutor demanding an explanation for Iceland's cooperation in "what is widely recognized to be US-led political persecution against foreign members of the press, including Icelandic citizens".
The press release also disclosed that the first substantial hearing on Assange's extradition request will commence on 14 June, the last day of the extradition request deadline. The hearing was earlier scheduled for 12 June.
