WikiLeaks founder Julian Assange on Monday denounced last week’s U.S. intelligence report on Russian hacking, calling it a politically motivated “press release” that provided no evidence that Russian actors gave WikiLeaks hacked material.

In an online news conference, Assange said the report is vague and that U.S. intelligence officials should be embarrassed by the 25-page, declassified document. “This is a press release,” Assange said. “It is clearly designed for political effects.”

The report accuses Russia of trying to interfere with the U.S. political process, with actions that included hacking into the email accounts of the Democratic National Committee and individual Democrats like Hillary Clinton’s campaign chairman John Podesta. The report said Russia also used state-funded propaganda and paid “trolls” to make nasty comments on social media services, although there was no suggestion that Russia affected the actual vote count.

The report, for the first time, explicitly tied Russia President Vladimir Putin to the hackings. It called Russian activities the “boldest effort yet” to influence a U.S. election, and said the Russian government provided emails to WikiLeaks — something Assange denied again on Monday. The report said Russian intelligence agencies gave stolen Democratic National Committee emails to WikiLeaks, which then released them to the public.

“As we have already stated, WikiLeaks’ sources with relation to the John Podesta and DNC leaks are not state parties,” Assange said. “They do not come from the Russian government.”

He did not provide any clues about the source of the documents, so it was unclear whether they could have been provided to WikiLeaks from Russian proxies.

The report lacked details about how the U.S. learned what it says it knows, such as any intercepted conversations or electronic messages from Russian leaders, including Putin, or about specific hacker techniques or digital tools the U.S. may have traced back to Russia in its investigations.
