WikiLeaks on Sunday took President Donald Trump to task for refusing to release his tax returns and offered to post them online, after a senior adviser said definitively that Trump would not be publicly disclosing the documents.

“Trump's breach of promise over the release of his tax returns is even more gratuitous than Clinton concealing her Goldman Sachs transcripts,” WikiLeaks wrote on Twitter.


The group also encouraged the leak of the documents. "Trump Counselor Kellyanne Conway stated today that Trump will not release his tax returns. Send them to: https://wikileaks.org/#submit so we can," another tweet read.

It was an interesting rebuke from WikiLeaks after Trump has appeared to side with founder Julian Assange in pushing back against U.S. intelligence officials’ conclusion that Russia President Vladimir Putin directed cyberattacks on Democratic targets in the U.S. to try to tilt the election Trump’s way.

Earlier on Sunday, Conway, the counselor to Trump, firmly said Trump will not be releasing his tax returns. Before he took office, Trump had used a different line, saying he couldn’t yet disclose the documents because they were under a routine audit.

In an interview on ABC's "This Week," Conway said the controversy over the tax returns was an attempt to re-litigate the presidential campaign.

"The White House response is that he’s not going to release his tax returns," Conway said.

"We litigated this all through the election. People didn’t care," Conway said. "They voted for him, and let me make this very clear: Most Americans ... are very focused on what their tax returns will look like while President Trump is in office, not what his look like."

Calls for Trump to disclose his tax returns have continued since his election, with critics saying the move would clarify whether he has any foreign conflicts of interest.

Trump's team has pushed back, arguing he's taken the necessary steps to separate himself from his business interests.

"President Trump and his family are complying with all the ethical rules, everything they need to do to step away from his businesses and be a full-time president," Conway said Sunday.
