WikiLeaks founder Julian Assange: 'No proof' Russian intelligence responsible for DNC hack

WikiLeaks founder Julian Assange says "there is no proof whatsoever" that Russian intelligence is behind the thousands of hacked emails from the Democratic National Committee that WikiLeaks released.

"The real story is what these emails contain and they show collusion," Assange said during an interview with NBC News that will air Monday night on "NBC Nightly News with Lester Holt."

While three cybersecurity experts told NBC that the DNC emails were hacked by Russian intelligence, Assange stressed that Wikileaks has not disclosed the source of the leak.

"Well there is no proof of that whatsoever. We have not disclosed our source, and of course, this is a diversion that's being pushed by the Hillary Clinton campaign," he said in an interview.

Since the emails came to light, Debbie Wasserman Schultz has announced she will resign as chair of the Democratic National Committee.

Wasserman Schultz came under fire after emails showing officials from the DNC plotted against Vermont Sen. Bernie Sanders' presidential campaign.
