Story highlights

The remark came at the end of a contentious interview with "Real Time" host Bill Maher

Trump has repeatedly refused to release his tax returns to the public

(CNN) —  

WikiLeaks on Saturday walked back a claim made by its founder, Julian Assange, that it was “working on” obtaining Donald Trump’s undisclosed tax returns.

Assange’s remark came at the end of a contentious interview Friday with “Real Time” host Bill Maher, during which the two discussed WikiLeaks’ recent disclosure of Democratic National Committee emails and voicemails. Assange, who has vowed to release more information to damage Hillary Clinton’s campaign, was asked by Maher, a Clinton supporter, whether he plans to similarly disrupt Trump’s presidential prospects.

“Why don’t you hack into Donald Trump’s tax return?” Maher asked.

“Well, we’re working on it,” responded Assange, who did not provide further information.

But a message from WikiLeaks’ official Twitter account Saturday morning dismissed Assange’s statement, claiming it was meant in jest.

“WikiLeaks isn’t ‘working on’ hacking Trump’s tax-returns. Claim is a joke from a comedy show. We are ‘working on’ encouraging whistleblowers.”

Trump has repeatedly refused to release his tax returns to the public, a common practice for modern presidential candidates, saying he’s under audit.

The bucking of the decades-long tradition has fueled considerable criticism and speculation over what the documents might contain, including whether Trump has any business dealings with Russia.

The US rival has been accused of being behind the hacked DNC emails, and the resulting controversy led to the resignation of DNC Chairwoman Debbie Wasserman Schultz and the ouster of several other top DNC officials. Assange told CNN last week his organization has “more material related to the Hillary Clinton campaign.”
