WikiLeaks founder Julian Assange mocked the Obama administration’s unclassified report on the cyberattacks against the Democratic party during the 2016 elections, and called it “a press release” that failed to prove Russia was behind the hacks.

The unclassified report stated that Russian President Vladimir Putin ordered the hacks as part of “an influence campaign” designed to “denigrate” Hillary Clinton, who had impugned the fairness of the 2011 Russian elections that kept Putin in power. It did not publish the evidence for these assessments, and cited the need to protect “sensitive sources or methods,” but it was released after President-elect Trump received a briefing on the classified version of the report.
