Müller's office has a deadline on Friday to explain to the court why Manafort has been charged with lying to investigators and breaking his cooperation agreement. Regardless, the Attorney General and the Attorney General in New York must provide memos to propose a penalty for Cohen – submissions that are expected to detail how he has cooperated in several investigations.
Mueller's memoranda comes in the same week The Special Representative's office told the court on Tuesday that Trump's former national security adviser, Michael Flynn, had "considerable support" for the Special Envoy's office and was not to receive a jail term.
In addition, former FBI director James Comey bears witness behind closed doors Friday before the House Judiciary and Oversight Committees for a Republican-led investigation into the causes of the FBI's investigation in Russia. Also on Friday, George Papadopoulos ̵
This adds up to one of the busiest weeks in the 19-month Mueller investigation – and possibly one of the most insightful.
Manafort Pleasure Agreement
The Special Adviser must now explain exactly why he believes Manafort lied and what he lied about.
The key question is whether Manafort has lied in relation to alleged collisions between the two Russian government and the Trump campaign.
Manafort maintains extensive relations with pro-Russian Ukrainian politicians, who have been around for a decade, and has been in close contact with a political agent connected with Russian intelligence, Kon Stantin Kilimnik, this year. His years of winning millions with the Ukrainian political advice led to his conviction for tax fraud and bank crimes this summer. After this conviction, Manafort admitted several lobbying and economic crimes and agreed to help Mueller.
Manafort lied "on various topics" after meeting with them several times. The prosecutors alleged last week in a court. Manafort has denied the allegation that he lied.
A spokesman for the Special Representative's Office said at least part of the Manafort memo will be published. As in Flynn's case earlier this week, part of it could be sealed if the details revealed details of ongoing investigations.
Condemnation of Cohen
The Special Lawyer could also uncover new information about his investigation if it delivers a memo Friday recommending a penalty for Cohen.
Cohen's case changed last week when he pleaded guilty to lied to Congress about the extent of Trump's talks about Trump Tower Moscow, which he had ended in January 2016. In fact, the discussions on the project ran so long in June 2016, revealed his plea, and Cohen said in court that he had lied "out of loyalty to Individual-1," an allusion to Trump.
Cohen pleaded guilty to US Attorney's Office earlier this year in a separate case from Manhattan. As part of his plea with this office, Cohen was faced with a probable sentence of 46 to 63 months, but his newly formulated cooperation agreement with prosecutors could significantly reduce this.
Mueller does not recommend a prison for Flynn
 On Tuesday, Mueller's team released some new details about the investigation when Flynn did not recommend imprisonment – and was left to the imagination. Long editorial teams reported in detail on the "significant support" Flynn gave to the Department of Justice.
Müller's conviction statement stated that Flynn had been interviewed 19 times and that he provided information for at least three investigations. However, some details of the investigation were completely revised in the document, except that it was a "criminal investigation".
"While this addendum seeks a comprehensive description of the benefits the government has received so far from the defendants. Emagazine.credit-suisse.com/app/art … = 118 & lang = DE Some of these benefits may be not fully implemented, as the investigations in which it has provided assistance have not yet been completed, "wrote the prosecutor.
Nonetheless, the prosecution said that Flynn's early collaboration was "particularly valuable" because of his insight and the fact that his collaboration also encouraged others to talk.
Flynn was Trump's first national security adviser, but was dismissed less than a month later. His term was due to the misleading White House because of his talks with the then Russian ambassador to the US, Sergey Kislyak.
Flynn pleaded guilty to lying to federal investigators in December 2017. He is sentenced on 18 December.
