US President Donald Trump on Saturday again denied that his presidential campaign colluded with Russian operatives, but made no comment on claims that he directly organized hush payments to ward off a possible sex scandal during his White House run.

Trump took to Twitter, his favorite means of communication, to address the multiple court filings that dropped on Friday in connection with special counsel Robert Mueller's sweeping investigation into Russian meddling in the 2016 election.

"AFTER TWO YEARS AND MILLIONS OF PAGES OF DOCUMENTS (and a cost of over $30,000,000), NO COLLUSION!" the president said.

While the filings indeed did not appear to reveal evidence of collusion, they did offer a wealth of new information about what Mueller's team is looking into, along with other federal prosecutors in New York.

Prosecutors directly implicated Trump in efforts to buy the silence of two women who claimed they had had affairs with him, saying he directed his then-attorney Michael Cohen to offer them hush money.

"With respect to both payments, Cohen acted with the intent to influence the 2016 presidential election," the New York prosecutors said.

"In particular, and as Cohen himself has now admitted, with respect to both payments, he acted in coordination with and at the direction of Individual-1," they added, referring to Trump.

The payments are technically unrelated to the Russia probe, but prosecutors painted a damning picture of the "extensive, deliberate, and serious criminal conduct" of Cohen -- once a member of Trump's inner circle of trusted aides.

In August, the 52-year-old Cohen pleaded guilty to violating campaign finance law in connection with the payments.

"Cohen deceived the voting public by hiding alleged facts that he believed would have had a substantial effect on the election," prosecutors said.

'Synergy on a government level'

Russians reached out to Donald Trump's then-personal lawyer Michael Cohen in November 2015 seeking to establish cooperation with his election campaign, Special Counsel Robert Mueller said

In a separate sentencing memo, Mueller said that Cohen was in contact with a Russian national as far back as November 2015 -- months before Trump formally won the presidential nomination and well before previously reported contacts -- who offered "synergy on a government level."

That Russian national claimed to have ties to the Kremlin and repeatedly proposed a meeting between Trump and Russian President Vladimir Putin.

The individual said the meeting could have a "phenomenal" impact "not only in political but in a business dimension as well," but Cohen never followed up, Mueller said.

That combination of political and business interests could spell trouble for Trump, whose real estate empire was seeking to build a signature tower in Moscow as late as mid-2016 in the midst of his White House bid.

Last week, Cohen pleaded guilty to lying to Congress about the Moscow real estate project.

Recent filings in the Mueller probe have suggested the White House knew that Cohen planned to lie to lawmakers about his contacts with Russians.

Due to his "relevant" and "substantial" help, Mueller declined to recommend additional jail time, but Cohen is still expected to face four to five years behind bars.

Multiple 'lies'

Paul Manafort, Donald Trump's former campaign manager seen here in July 2016, has been convicted mostly on charges related to his work for pro-Moscow politicians in Ukraine between 2004 and 2014

Also on Friday, new twists and turns emerged in the case against Trump's onetime campaign manager Paul Manafort, who was convicted in August of financial fraud and witness tampering charges and pleaded guilty to a second set of charges a month later.

Prosecutors accused Manafort of multiple "lies" to investigators: about his contacts with administration officials even after striking a plea deal; about a debt payment; and about his interaction with a suspected Russian intelligence officer.

The breach of the plea deal could lead to a stiffer jail sentence than the 10 years originally envisaged for the 69-year-old veteran Republican consultant.

Manafort has been convicted mostly on charges related to his work for pro-Moscow politicians in Ukraine between 2004 and 2014.

But he has also been investigated for his possible role in alleged campaign collusion with Russia during the election.

Mueller has been inching ever closer to the White House, and on Friday, Trump fired off a feverish volley of tweets against a probe he dubs a "witch hunt," accusing Mueller of "big time conflicts of interest" and alleging he coerced false testimony from witnesses.

For House Democrat John Garamendi, these may be "the opening days of an impeachment."

Trump is a president who "clearly has surrounded himself with criminals," he told CNN.

"During the campaign, laws were broken... And now we have the president implicated in that," he said.
