Former National Security Adviser Michael Flynn is seeking to formally withdraw his guilty plea, court filings revealed Tuesday. Flynn, who served briefly in the Trump administration, was charged in former Special Counsel Robert Mueller's investigation into 2016 Russian election interference more than two years ago. He initially said he lied to federal agents about his contacts with a Russian diplomat, but is now looking to change course. His attorneys reportedly said the decision was made because prosecutors broke their side of their plea bargain. His sentencing was planned for Jan. 28, but is now likely to be postponed. Flynn's filing does not result in an automatic plea withdrawal; a judge must approve.
