Donald Trump's personal lawyer Michael Cohen was in contact with a Russian seeking quote "synergy" with his 2016 presidential campaign.
That's among the new revelations in a flurry of court filings on Friday (December 7) by prosecutors examining whether Trump's campaign colluded with Moscow.
It looks like Trump's self described fixer has been giving prosecutors extensive details about the inner workings of Trump's business.
And for the first time, prosecutors themselves are suggesting Trump may have been involved in criminal behavior.
In a sentencing document, Special Counsel Robert Mueller said a Russian person reached out to Cohen as early as November 2015, offering quote 'synergy on a government level' -- saying it could pay dividends for Trump in business and politics.
Mueller says Cohen did not follow up.
Cohen has been cooperating with prosecutors after he pleaded guilty to funneling hush money to porn star Stormy Daniels and another woman who both say they had affairs with Trump.
For the first time on Friday, prosecutors saying Trump, who's described as Individual 1 in the court filing, directed Cohen to break campaign finance laws as part of that effort.
That echoes an earlier admission by Cohen.
Cohen last week pled guilty in a second criminal probe -- admitting he lied about a potential deal to build a Trump Tower in Moscow.
That deal could have brought Trump's business hundreds of millions of dollars from Russian sources, Mueller said.
Cohen, due to be sentenced in both cases next week.
Despite the cooperation, prosecutor suggesting he serve four years saying he didn't share everything he knew.
Cohen's cooperation a contrast to Trump's former campaign manager, Paul Manafort.
In a separate court filing Friday, Mueller saying that Manafort lied to his team about five subjects -- including his contacts with administration officials.
Trump has denied any collusion between his campaign and Russia and regularly refers to the probe as a witch hunt.
On Friday he said his legal team is working on its own report to counter Mueller's findings.
There are additional clues in these filings -- Mueller says Cohen has been providing helpful information about other people who worked for Trump's business -- and people who have worked in his White House.
That's sure to set off more alarm bells among people closest to the President.
