The whistleblower dropped the bombshell before an interview with Fox News host Sean Hannity at the Ecuadorian Embassy where he is living under political asylum.
WikiLeaks said, “If you thought 2016 was a big WikiLeaks year, 2017 will blow you away” adding that “a showdown is coming”.
Many believe this was a warning of a new shock bombshell that will be revealed in tonight’s televised interview with the WikiLeaks founder.
The Express reports: A constant stream of WikiLeaks emails hit Hillary Clinton’s campaign and helped turn public opinion against her, paving the way for Donald Trump’s victory.
But in tonight’s interview, Mr Assange will assure the American people that the Russian Government was not its source for leaks during the US election campaign.
WikiLeaks released tens of thousands of emails from the Democratic National Convention (DNC) and Mrs Clinton’s campaign manager John Podesta.
In a clip of tonight’s Fox News interview, Mr Hannity asks if the DNC and Podesta emails were from “Russia or anyone associated with Russia”.
Mr Assange replies: “We can say, we have said, repeatedly that over the last two months that our source is not the Russian government and it is not a state party.”
US intelligence agencies have now concluded that Russia ordered hackers to carry out cyber attacks in a bid to help Donald Trump win the election in November.
Outgoing Democratic President Barack Obama has since expelled Russian diplomats in retaliation for suspected hacking and meddling in the election.
“They’re trying to delegitimize the Trump administration as it goes into the White House.”

Mr Hannity, who supports Mr Trump, once accused Mr Assange of “waging war against the US” but their relationship has since warmed.
The computer hacker appeared on Mr Hannity’s show in early December to deny Russian involvement in the hacking.
He has been living in the Ecuadorian Embassy for more than four years after being granted asylum in order to avoid extradition over allegations that he raped a woman and molested another in Sweden.
