The court order was issued after prosecutors admitted accidently altered documents -- notes written by former FBI agent Peter Strzok and former FBI deputy director Andrew McCabe -- were used.
"The government has acknowledged that altered FBI records have been produced by the government and filed on the record in this case," noted Judge Emmet Sullivan
The order from Sullivan comes as the government again requested the judge dismiss the criminal case against Flynn, a move Sullivan has so far resisted.
It’s the latest twist in a case where the former Trump national security adviser pleaded guilty twice to lying to the FBI about his contacts with Russian officials. Flynn has since tried to withdraw the plea, and the Justice Department has sought to have the charges dismissed.
Flynn’s legal team has long clashed with Sullivan. Earlier this month, Flynn demanded in a new court filing that Sullivan should recuse himself from "further participation" in his case, citing an "appearance of bias," which his legal team cast as "terrifying and mandates disqualification."
"The circumstances of this case lead any reasonable observer to believe that the current judge has a personal interest in the outcome, is irreparably biased against general Flynn, and is actively litigating against him," according to the filing.
