A court document partially unsealed Thursday revealed some of what special counsel Robert Mueller’s team told a federal judge back in December about former National Security Advisor Mike Flynn’s cooperation.

The filing revealed that Flynn had “relayed” to prosecutors “statements made in 2016 by senior campaign officials to which only a select few people were privy.”

“For example, the defendant recalled conversation with senior campaign officials after the release of the Podesta emails, during which the prospect of reaching out to WikiLeaks was discussed,” the unsealed document said, referring to the emails of John Podesta, Hillary Clinton’s campaign chairman, which were leaked in October 2016.

The public version of the Mueller report goes into some detail about the discussions within the campaign and among its allies about WikiLeaks’ dissemination of Democratic emails hacked by Russia. However, much of that section is redacted. At least some of the redactions are believed to be related to Roger Stone’s case, where a judge has imposed a gag order.

The public version of the report included details of conversations between Jerome Corsi and Ted Malloch — two Trump allies who had no formal roles on the campaign — about the release of the Podesta emails. It also detailed Donald Trump Jr.’s communications with WikiLeaks over Twitter direct message in the days before and after the Podesta emails were released. Those messages had been made public well before Mueller’s report.

According to Mueller’s report, Trump Jr. sent an email to “variety of senior campaign staff” flagging for them a Twitter DM WikiLeaks sent him a few days before the Podesta emails were released.

The court document unsealed Thursday was filed back in December, before Flynn was set to be sentenced. The sentencing hearing took a dramatic turn however, when the judge railed against Flynn for a sentencing filing that seemed to cast doubt on his guilty plea, while expressing “disgust” and “disdain” with Flynn’s offense. Flynn got the judge’s permission to push back the sentencing until he was fully done cooperating with prosecutors.

The judge, U.S. District Judge Emmet Sullivan, unsealed the document, which still contains some redactions, on Thursday because the government had represented “that there no longer exists a compelling government interest to seal certain information in those records.”
