Martin H. Simon – Pool/Getty Images(WASHINGTON) — Special counsel Robert Mueller on Friday took the unusual step of publicly denying portions of a media report published by Buzzfeed News.

The article, posted Thursday night on Buzzfeed, suggests that President Donald Trump directed Michael Cohen, his former personal attorney and fixer, to lie in his testimony to Congress and that special counsel Robert Mueller has evidence to support that claim.

“BuzzFeed’s description of specific statements to the Special Counsel’s Office, and characterization of documents and testimony obtained by this office, regarding Michael Cohen’s Congressional testimony are not accurate,” special counsel spokesman Peter Carr said Friday evening in a brief statement to ABC News.

Buzzfeed’s editor-in-chief Ben Smith stood by his organization’s reporting, tweeting ” In response to the statement tonight from the Special Counsel’s spokesman: We stand by our reporting and the sources who informed it, and we urge the Special Counsel to make clear what he’s disputing.”

It was a position he reiterated later during an appearance on CNN.

Democrats in Congress pledged to investigate allegations in Buzzfeed ’s media report published Thursday night suggesting President Donald Trump instructed Michael Cohen, his former personal attorney and fixer, to lie to Congress about a proposed project to build a Trump-branded property in Moscow.

“These allegations may prove unfounded, but, if true, they would constitute both the subornation of perjury as well as obstruction of justice,” Rep. Adam Schiff, D-Calif., chairman of the House Intelligence Committee, said in a statement Friday morning.

BuzzFeed editor-in-chief Ben Smith stood by the organizations reporting on Friday tweeting “In response to the statement tonight from the Special Counsel’s spokesman: We stand by our reporting and the sources who informed it, and we urge the Special Counsel to make clear what he’s disputing.”

As part of his plea deal with Mueller, Cohen admitted that he made the misstatements about the Trump Organization’s “Moscow Project”, in an August 2017 letter to the House and Senate intelligence committees, which were conducting inquiries into alleged collusion between the Trump campaign and Russia.

ABC News has not confirmed the allegations in Buzzfeed’s story that Trump directed Cohen to lied to Congress.

Trump’s personal attorney, Rudy Giuliani, called Buzzfeed’s report “categorically false” and said “today’s claims are just more made-up lies born of Michael Cohen’s malice and desperation, in an effort to reduce his sentence.” White House press secretary Sarah Sanders on Friday called the allegations laid out by Buzzfeed “absolutely ridiculous.”

The chairman of the House Judiciary Committee, Rep. Jerry Nadler, D-N.Y., joined Schiff’s call to investigate, pledging that his committee will “get to the bottom of it.”

Others went further. Rep. Joaquin Castro, D-Texas, tweeted late Thursday that Trump “must resign or be impeached” if the Buzzfeed report is proven truthful. And Sen. Chris Murphy, D-Conn., called on special counsel Robert Mueller “to show Congress his cards before it’s too late for us to act.”

Much remains unknown about the plans for a Trump Tower in Moscow.

Cohen worked hand-in-hand with Felix Sater, a Russian-born business associate who scouted deals for the Trump Organization, to set in motion plans for a Trump Tower in Moscow. The two even conceived an idea to offer a $50 million penthouse in the prospective building to Russian President Vladimir Putin, a source familiar with the deal told ABC News.

The public first learned in the summer of 2017 that Cohen had been pursuing a deal to build a Trump Tower in Moscow even after his boss had begun to campaign for president.

At the time, Cohen told members of Congress the deal never progressed beyond an initial “letter of intent” and it was halted in January of 2016, before the Iowa caucuses.

But later, Cohen admitted in court that he made the false statements about the project “to be consistent with Individual 1’s political messaging and to be loyal to Individual 1.” Individual 1 was believed to be Trump, based on the description in court documents.

The president during the campaign denied working on any deals with Russia but tweeted late last year that he “lightly looked at doing a building in Moscow.”

Cohen was sentenced in December to three years in prison for financial crimes, lying to Congress, and for two violations of campaign finance law.

He’s scheduled to report to prison in early March, but he could have a busy month of congressional testimony before then.

He has already agreed to appear publicly before the House Oversight and Reform Committee on Feb. 7, and Schiff has expressed interest in bringing Cohen back to the House Intelligence Committee for an interview behind closed doors.

On Friday morning, Sen. Mark Warner, D-Va., vice chairman of the Senate Intelligence Committee, said “we expect to have him back… in February, we’ve got a lot of questions to ask.”
