Special advocate Robert Mueller said Friday in a new case that prosecutors had evidence that Trump's former advisor, Roger Stone, had contacted WikiLeaks, the organization that had released hacked emails for the Democrats during the 2016 campaign.
Stone – who was indicted last month for obstruction, false statements and tampering with witnesses – denied Fox News the existence of evidence of such communications.

"There is no such evidence," Stone said in a text message.
In a Friday motion, Mueller's team said that "search warrants were executed on accounts containing Stone's communications" with an organization widely regarded as WikiLeaks.
The indictment last month does not accuse Stone of conspiring with WikiLeaks, the anti-secret website that has published the emails, nor with Russian agents, said Mueller, allegedly hacked them. Instead, he accuses him of tampering with witnesses, obstruction and false statements about his interactions related to the release of WikiLeaks.
The indictment says that Stone spoke of WikiLeaks to the Trump campaign officials in the summer of 2016 and information available to the organization that could harm the Clinton campaign. He also said Stone was contacted by "Trump campaigners" to inquire about future WikiLeaks publications of hacked Democrat emails.

Stone pleaded not guilty to the charges.
Earlier Friday, Justice Amy Berman Jackson of the Federal Court of the District of Columbia ordered that Mr. Stone refrain from making statements to the media or in public places likely to cause material injury to the present case.
Jackson also ordered all participants in the case, including the witnesses and the lawyers, to "refrain" from making statements to the media or the public, which could influence any juror, juror, judge, witness or officer of justice or interfere with the administration of justice. "
