President Donald Trump's former national security adviser provided so much information to the special counsel's Russia investigation that prosecutors say he shouldn't do any prison time, according to a court filing on Tuesday that describes Michael Flynn's cooperation as "substantial."
The filing by special counsel Robert Mueller provides the first details of Flynn's assistance in the Russia investigation, including that he participated in 19 interviews with prosecutors and cooperated extensively in a separate and undisclosed criminal probe.
It was filed two weeks ahead of Flynn's sentencing and just over a year after he became the first of five Trump associates to accept responsibility by pleading guilty to lying to the FBI about conversations with the Russian ambassador.
Though prosecutors withheld specific details of Flynn's cooperation because of ongoing investigations, their filing nonetheless underscores the breadth of information Mueller has obtained from people close to Trump as the president increasingly vents his anger at the probe - and those who cooperate with it.
This week, Trump lashed out at his former legal fixer, Michael Cohen, saying he is making up "stories" to get a reduced prison sentence after his latest guilty plea to lying to Congress. Trump also praised longtime confidante Roger Stone for saying he would "never testify against Trump," adding in his tweet, "Nice to know some people still have 'guts!'"
It's unclear if Trump will now turn his fury on Flynn, whom Trump grew close to during the 2016 campaign and who has drawn the president's sympathy since he came under investigation.
Trump has repeatedly lamented how Flynn's life has been destroyed by the special counsel's probe. At one point, he tried to protect Flynn by asking former FBI Director James Comey to drop an investigation into his alleged false statements, according to a memo Comey wrote after the February 2017 encounter.
That episode, which Trump has denied, is among those under scrutiny by Mueller as he probes whether the president attempted to obstruct the Russia investigation.
Federal sentencing guidelines recommend between zero and six months in prison for Flynn, leaving open the possibility of probation.
Mueller's office said Flynn's cooperation merits a sentence at the bottom end of that range.
But prosecutors also say the long military and government service that sets him apart from all other defendants in the investigation makes his deception even more troublesome.
