Cohen also suggested that Mueller may have the evidence to back up his revelation.

Stone has denied Cohen’s new allegation. WikiLeaks has also disputed the account, saying that Stone and Assange have never spoken.

Questions surrounding the WikiLeaks release of stolen Democratic National Committee (DNC) emails ahead of the Democratic convention have been a staple of both the congressional and special counsel inquiries into Moscow’s election meddling. The group also released hacked emails from Clinton campaign chairman John Podesta weeks ahead of the 2016 vote.

Multiple members of the Senate Intelligence Committee, which privately questioned the former lawyer this week, declined to comment on what they learned during their closed-door interview.

But they indicated that the WikiLeaks revelation is a claim they’ll be looking into.

“Obviously when somebody tells you the truth about things they said weren’t the truth, it should lead you in other directions,” he said.

Others weren’t so quick to buy Cohen’s story.

“If [Stone] thought he was doing something wrong, then maybe you could say ‘oh well he didn’t want to bring Trump in,’ ” Swalwell said. “If he honestly didn’t think he was doing anything wrong, then why wouldn’t he tell him about something he spent so much time working on?”

Mueller’s investigation has also focused on WikiLeaks’ email dumps. The special counsel has indicted 12 Russian military officers in the hack of the DNC. And he charged Stone earlier this year with making false statements to Congress, obstructing a congressional investigation and witness tampering over his statements on WikiLeaks.

Stone made statements during the 2016 election that appeared to show that he had prior knowledge of the WikiLeaks email dump. He has since said that he had a back channel tipping him off about the organization's actions.

Stone has denied the charges and is now preparing for a legal battle with the special counsel. And while he hasn’t been charged in relation to WikiLeaks’ actions themselves, it remains possible that Mueller could still indict him in the case, if he has evidence showing that Stone committed a crime.

Trump also declared "I love WikiLeaks!" at a 2016 campaign rally just days before the election, as he read aloud from hacked Democratic emails published by the organization.

But Trump has repeatedly denied having any prior knowledge of the emails' release: He told The New York Times earlier this year that he had never discussed WikiLeaks with Stone, a marked departure from Cohen's testimony.

Cohen said during his public hearing with the Oversight and Reform Committee on Wednesday that he has met with Mueller’s team seven times since agreeing to cooperate with investigators.

Mueller also suggested in a court filing last month that he has evidence of Stone communicating with WikiLeaks. Stone at the time claimed that evidence only referred to messages he exchanged with WikiLeaks after the 2016 election.

And there’s speculation that Assange, the head of WikiLeaks, is already facing charges in the U.S. that have been filed under seal, after a filing in a separate case mistakenly referred to him by name.

Those charges could refer to classified documents released by WikiLeaks under Assange’s watch. But it’s another sign that the organization is under intense pressure from the U.S. federal government.
