In a tweet on Friday from the WikiLeaks Twitter account, the whistleblowing website encouraged Obama to “submit any Putin documents” to them so they can “be authenticated to our standards if he wants them to be seen as credible.”

The tweet comes only a day Obama told NPR, “there is no doubt that when any foreign government tries to impact the integrity of our elections that we need to take action.”

The president has ordered a full review into the hacking and expects it will give “a comprehensive and best guess as to those motivations,” behind the leaks.

The Washington Post published an article last week featuring claims by anonymous CIA officials that Russia had “intervened in the 2016 election to help Donald Trump.” It quickly came under public scrutiny, as people were wary of trusting anonymous claims without evidence, given the intelligence agencies’ historyoflying to the public.

The Washington Post’s owner, Jeff Bezos’s, also has contracts with the CIA worth $600 million, more than double what he paid for the Post.

There have been calls for the intelligence agencies to produce evidence of Russian government hacking the DNC.

Speaking to Fox News’ Sean Hannity on Thursday, WikiLeaks founder Julian Assange clearly stated, “Our source was not the Russian government.”

Addressing claims that WikiLeaks chose not to release similarly damning information about Republicans during the election, Assange also said that the site had received about three pages on the RNC, but that the information had already been published.

The WikiLeaks editor went on to say they were unhappy to even have to say that the documents did not come from a state party, as their usual policy is not to say anything about the source of leaks. In this case, they were forced to do so to prevent further distraction from the content of the documents.

Former UK Ambassador to Uzbekistan and WikiLeaks insider Craig Murray said he knows for a fact that the DNC leak came from an insider and not a foreign hacker.

“Very, very few people can be said to definitely have access to the source of the leak,” he said. “The people saying it is not Russia are those who do have access.”
