In a new and expected sentencing memo Tuesday night, Special Counsel Robert Mueller revealed that he was pleased with former national security adviser Michael Flynn's cooperation in the Russian Federation investigation.
The special counsel is also due to make three crucial court filings this week, including sentencing memos for Michal Flynn, Michael Cohen and Paul Manafort.
Mueller's office says Flynn assisted them 'on a range of issues, including interactions between individuals in the Presidential Transition Team and Russian Federation'.
Prosecutors said Flynn also provided help on other criminal investigations, although those details were redacted from the filing because the probes are ongoing.
Flynn pleaded guilty one year ago to lying to the Federal Bureau of Investigation about his contacts with Sergey Kislyak, who was then the Ambassador of Russian Federation. In the same document, he goes further than in documents released last week by Special Counsel Robert S. Mueller III's office in which Cohen admitted to lying to Congress about his work on behalf of Trump when he was a candidate as he tried to secure approval for a hotel project in Moscow. The sentencing guidelines for Flynn's offense suggest 0 to 6 months of incarceration.
Cohen pleaded guilty in August to five counts of tax evasion, one count of making a false statement to a bank and two campaign finance violations, admitting that he and the chief executive of a media company worked in the summer of 2016 to keep an individual from publicly disclosing information that could hurt Trump's campaign.
US President Donald Trump has called for a "full and complete" sentence for his former lawyer Michael Cohen, weighing in on a judicial proceeding with accusations Cohen lied about dealings with Russian Federation during his 2016 presidential campaign. The discussions related to sanctions then president Barack Obama had imposed on Moscow over its interference in the United States election, and a United Nations security council vote on halting new Israeli settlements.
He noted at the time that his former lawyer faces a long sentence and was merely trying to reduce it by accepting the plea deal. His sentencing is set for December 18. One knowledgeable source said the bulk of Flynn's cooperation with the special counsel occurred immediately following his December court appearance.
Those contacts, including with a top aide to President Vladimir Putin, continued throughout the first half of 2016 even after Trump secured the Republican nomination for president, Cohen admitted - contradicting claims by Trump that there were no dealings beyond 2015.
But Manafort could be facing a tough sentence after prosecutors alleged last month he had breached his plea deal by lying repeatedly to the Federal Bureau of Investigation.
Trump has tweeted in the past in support of Flynn, saying that Mueller had "totally destroyed" his life unfairly.
