"Cohen made the false statements to (1) minimize links between the Moscow Project and (President Trump) and (2) give the false impression that the Moscow Project ended before 'the Iowa caucus and. the very first primary, ' in hopes of limiting the ongoing Russian Federation investigations".
Mr Cohen said in his statement to Congress he had claimed to have had limited contact with Mr Trump concerning the project, when in fact it had been "more extensive".
Trump's refusal to take a pardon off the table came after special counsel Robert Mueller issued a new court filing Monday night that alleged Manafort had repeatedly lied to federal investigators "on a variety of subject matters", which was a breach of his plea deal.
"Michael Cohen is lying and he's trying to get a reduced sentence for things that have nothing to do with me", he said. Cohen had told a Senate committee that a Trump Organization development in Moscow had "ended in January 2016 and was not discussed extensively with others" inside the organization.
Trump has denied publicly he had any knowledge at the time and he said as much in written answers recently to Mueller's office, according to reports on Wednesday.
He told the judge he lied about the timing of the negotiations and other details to be consistent with Trump's "political message".
Oh, and as journalists are noting, if Cohen is guilty of lying to Congress, that means Don Jr.is too.
"This was a deal that didn't happen", Trump said of the purported real estate project.
Mr Mueller's team confirmed Mr Manafort had breached his plea deal with the special counsel by lying to federal investigators.
There will also now be increased scrutiny into whether the president misled the public with statements like "I have no dealings with Russian Federation".
Cohen has been cooperating with Mueller's probe.
He pleaded guilty to a slew of financial crimes, including campaign finance violations stemming from hush money payments Cohen made to women on Trump's behalf.
The US says the emails were hacked by Russian intelligence which supplied them to WikiLeaks, aiming to tilt the election in Trump's favor.
The nine-page charging document for Cohen traces the behind-the-scenes communication about the project that nearly became reality in October 2015 when an obscure Russian real estate developer signed a letter of intent sent by Cohen for a 15-floor hotel, condominium and retail complex in Moscow.
Cohen's guilty plea comes the same day that ABC News reported that he has also reached a tentative deal with special counsel Robert Mueller in the Russian Federation investigation. "Michael Cohen is a liar", said Trump lawyer Rudy Giuliani. He previously identified individual 1 as Trump.
Cohen has been scheduled to be sentenced in the earlier matter on December 12.
