President Donald Trump's former lawyer, Michael Cohen, was in touch as far back as 2015 with a Russian who offered "political synergy" with the Trump election campaign and proposed a meeting between the candidate and Russian President Vladimir Putin, the federal special counsel said.
"The government's filings in Mr. Cohen's case tell us nothing of value that wasn't already known", Sanders said.
But also, significantly, the memo documents Cohen's claims that he was operating at the behest of Trump when he paid off two women Trump allegedly had affairs with to keep them from going to the press during the 2016 presidential campaign.
Filings by prosecutors from both NY and the Trump-Russia special counsel's office laid out for the first time details of the cooperation of Cohen, a vital witness who once said he'd "take a bullet" for the president but who in recent months has become a prime antagonist and pledged to come clean with the government.
Initially, Cohen said his September 2015 comments on Sean Hannity's radio show predicting a "better than likely chance" that Trump would meet Putin that week at the UN General Assembly were "spontaneous and had not been discussed within the campaign".
Cohen, an attorney and businessman, committed four distinct federal crimes over a period of several years. Mueller's memo says Cohen has met with the special counsel's office in seven different sessions to provide valuable information. In doing so, they'll have to provide a federal judge with at least some description of the assistance he's provided to their investigations - the Russian Federation probe and a separate investigation led by the US attorney's office in Manhattan.
"Totally clears the president".
Dean's comments, made during CNN's "Erin Burnett OutFront" segment, follow the release of a legal memo from federal prosecutors in NY regarding Trump's former personal lawyer, Michael Cohen.
In Washington, Mueller also detailed multiple "lies" that former Trump campaign chief Paul Manafort, 69, told investigators, leading to a termination of his cooperation deal and the likelihood of a stiff prison sentence.
The filing says the meeting never happened. Though he has portrayed himself as cooperative, "his description of those efforts is overstated in some respects and incomplete in others", prosecutors said.
Mueller said on Friday that Cohen repeated his false statements about the project in his first meeting with Mueller's office, admitting the truth only in a later meeting in September after he had pleaded guilty to the separate NY charges.
He said the worst-case scenario for the president, on the other hand, would be if Mueller has yet-unseen evidence of criminal conduct.
However, in the crimes to which he pleaded guilty in August, he was motivated "by personal greed and repeatedly used his power and influence for deceptive ends".
