Last night he said they "totally clear the President".
He had provided information about contacts with Russian interests during the campaign, attempts by Russians to reach the campaign and about contacts with "persons connected to the White House" in 2017-2018, the filing added.
Prosecutors in NY, where Cohen pleaded guilty in August in connection with those payments, said the lawyer "acted in coordination and at the direction" of Trump.
In August, 52-year-old Cohen pleaded guilty to violating campaign finance law in connection with the payments.
A separate court document filed Friday evening, in which Mueller's team argued that Manafort had breached a plea agreement by lying to them, also contained multiple references to his contact with Russian-Ukrainian political consultant Konstantin Kilimnik, although most of the details of those contacts are blacked out in the publicly available version of the document.
U.S. prosecutors have revealed that a Russian offered cooperation to Donald Trump's campaign as early as 2015, declaring that the president's ex-lawyer Michael Cohen had provided "relevant" and "substantial" help to the Russia investigation.
The memo from NY prosecutors identifies three people at an August 2014 meeting: Cohen, "Individual 1" and "Chairman 1".
Dean, who served time in prison for his involvement in the Watergate scandal, was discussing a sentencing memo from the Manhattan US attorney's office, which was the first time prosecutors have said Cohen acted at the direction of Trump when the former fixer made payments to silence women who claimed to have had affairs with Trump prior to his time running for office.
Prosecutors working for the U.S. Attorney's Office for the Southern District of NY based in Manhattan asked a judge to impose a sentence that reflects a "modest downward variance" from the potential maximum of 63 months in prison that Cohen faces.
Trump's only defense? Cohen, he says, is a liar.
A heavily redacted court filing said that Manafort's "lies" included untruths about his dealings with Konstantin Kilimnik, a business associate who USA officials suspect is a Russian intelligence operative, and about his contacts with Trump administration officials after striking a plea agreement.
But the Mueller team credits Cohen with cooperating with special prosecutors in their investigation into Russian meddling.
Manafort resigned from his job on the Trump campaign as questions swirled about his lobbying work for a pro-Russia political party in Ukraine. "But Cohen's description of those efforts is overstated in some respects and incomplete in others". "Thank you!" he tweeted shortly after the report's release.
"After cheating the IRS for years, lying to banks and to Congress, and seeking to criminally influence the Presidential election, Cohen's decision to plead guilty - rather than seek a pardon for his manifold crimes - does not make him a hero", acting U.S. Attorney Robert Khuzami wrote.
Cohen has admitted to lying to Congress about efforts by Trump's real estate company to build a project in Moscow as late as the summer of 2016, after Trump became the Republican nominee for president.
