He added: “Arguably, you sold your country out.”Flynn pleaded guilty last year to making false statements to the FBI, the first Trump associate to make a guilty plea so far in special counsel Robert Mueller’s investigation. He admitted to lying about his conversations with Russia’s ambassador to the United States during the transition period before Trump’s inauguration. “I want to be frank with you, this crime is very serious,” Sullivan said in the courtroom Tuesday. “Not only did you lie to the FBI, you lied to senior officials in the incoming administration.” Prosecutors from Mueller’s office asked the judge to give Flynn little to no jail time because he had cooperated extensively with them. But now it seems Flynn believes he can cooperate even more. His team now has until March 13 to file a status report with the court, and his sentencing date has yet to be rescheduled.
