WikiLeaks became an influential part of the 2016 presidential race with the release of thousands of emails from John Podesta, Hillary Clinton's campaign chairman. Some of those emails were used by Donald Trump at the third and final debate to accuse his rival of corruption and deception.
Now the secretive group has promised to release more documents meant to embarrass Clinton's running mate Tim Kaine, and Donna Brazile, the chairwoman of the Democratic National Committee.
But both are fighting back.
The cryptic tweet from Thursday.
Kaine has strongly hinted that Russia is behind the document leaks in an attempt to influence the U.S. election.
"I don't think it's funny when you have a nation like Russia that has engaged in activity to destabilize elections in countries," Kaine told CBS News.
Both Kaine and Brazile also believe that some of the "leaked" documents are in fact doctored or forged to add disinformation into the news cycle.
Trump has used the WikiLeaks documents to pummel Clinton.
Many fear that Trump's campaign is too close to Russian leader Vladimir Putin.
