Flynn took part in 19 interviews with Mueller's team.
The memo doesn't provide any insights into what Flynn told Mueller.
US Special Counsel Robert Mueller's office will make a sentencing recommendation for former national security adviser Michael Flynn on Tuesday, in a court filing that is expected to shed light on the extent of Flynn's cooperation in the Russian Federation probe.
Flynn, whose sentencing is scheduled for Dec. 18, pleaded guilty in December 2017 to lying to the Federal Bureau of Investigation about his conversations with then-Russian Ambassador Sergey Kislyak during the presidential transition period from election day 2016 to Trump's inauguration in January 2017.
It is now clear that Mueller is building a layered narrative, starting at the edge of the drama, by first exposing Russian election interference and fingering the culprits in Moscow's spy agencies. He also lied about discussing a United Nations resolution condemning Israeli settlements with Kislyak.
"Senior government leaders should be held to the highest standards", Mr Mueller writes.
Manafort, in contrast, breached his plea deal by lying repeatedly to the Federal Bureau of Investigation and Mueller's team, prosecutors alleged in a court filing last week. Mueller noted that Flynn later worked extensively with the special counsel's investigation, likely prompting other witnesses to be more forthcoming.
Trump has been quick to express his displeasure at former surrogates who have cooperated with the Mueller probe.
If the special counsel can prove that they in any way coordinated the timing of the WikiLeaks dump to take the heat off Trump at a moment when his entire campaign was in peril, it would strongly suggest collusion. The party's leadership has promised to vigorously pursue areas of investigation into Trump's finances and Trump team contacts with foreign actors, having accused the Republicans of choosing party loyalty over proper oversight the past two years.
Putin says if USA starts developing intermediate-range missiles, so will Russian Federation
If Russia is serious about preserving the treaty, the release added, it should discuss USA concerns over the 9M729 missile system. Stoltenberg said that he regretted seeing the INF come to a close.
Former Clinton pollster Mark Penn added that Mueller's office is getting people to plead guilty to charges in order to build a case against President Trump.
But Democrats, as well as some legal experts, disagreed.
Cohen and his attorneys also cited the payments he made to women who allegedly had affairs with Trump, strongly implying in their filing that President Trump is the person referred to as "Client-1"- which had widely been assumed. It's unclear how many of them deal with the Russian Federation probe.
Special Counsel Robert Mueller has recommended Flynn face little to no jail time, after assisting investigators. "That most of the details are redacted signals he has given far more than we or the President may know".
Prosecutors said Flynn also provided help on other criminal investigations, although those details were redacted from the filing because the probes are ongoing.
Typically, he explained, prosecutors only sentence defendants who have flipped when they no longer need them, in order to avoid any backsliding.
"It is a shame because his actions during the transition were lawful", Trump tweeted after Flynn pleaded guilty a year ago.
It does, however, divulge some new pieces of information, none of which are good for the President.
"The defendant provided firsthand information about the content and context of interactions between the transition team and Russian government officials", it noted.
Rudy Giuliani, President Donald Trump's attorney, downplayed any concerns following the release of special counsel Robert Mueller's latest court filings.
