The Mueller Report:
Beginning in the summer of 2016, Assange and WikiLeaks made a number of statements about Seth Rich, a former DNC staff member who was killed in July 2016. The statements about Rich implied falsely that he had been the source of the stolen DNC emails. On August 9, 2016, the @WikiLeaks Twitter account posted: “ANNOUNCE: WikiLeaks has decided to issue a US$20k reward for information leading to conviction for the murder of DNC staffer Seth Rich.” Likewise, on August 25, 2016, Assange was asked in an interview, “Why are you so interested in Seth Rich’s killer?” and responded, “We’ve very interested in anything that might be a threat to alleged WikiLeaks sources.” The interviewer responded to Assange’s statement by commenting, “I know you don’t want to reveal your source, but it certainly sounds like you’re suggesting a man who leaked information to WikiLeaks was then murdered.” Assange replied, “If there’s someone who’s potentially connected to our publication, and that person has been murdered in suspicious circumstances, it doesn’t necessarily mean that the two are connected. But it is a very serious matter…that type of allegation is very serious, as it’s taken very seriously by us.”
After the U.S. intelligence community publicly announced its assessment that Russia was behind the hacking operation, Assange continued to deny that the Clinton materials released by WikiLeaks had come from Russian hacking. According to media reports, Assange told a U.S. congressman that the DNC hack was an “inside job,” and purported to have “physical proof that Russians did not give materials to Assange."
