President Trump blasted BuzzFeed News late Friday night on Twitter — saying it was a “very sad day for journalism” — after the special counsel disputed the media outlet’s report on his alleged real estate deal with the Russians.

“Remember it was Buzzfeed that released the totally discredited ‘Dossier,’ paid for by Crooked Hillary Clinton and the Democrats (as opposition research), on which the entire Russian probe is based!” Trump tweeted. “A very sad day for journalism, but a great day for our Country!”

The president went on to say that “fake news is truly the ENEMY OF THE PEOPLE!” — and he also re-tweeted a pair of posts made by Geraldo Rivera, which ridiculed BuzzFeed as well.

“This is just the most egregious example of the rampant unfairness that has tainted this partisan witch-hunt from the beginning,” said the Fox correspondent. “The utter hatred for @realDonaldTrump has empowered a legion of back stabbers wielding flamboyant falsehoods to undermine @POTUS.”

Rivera added, “At what point in fairness-after 2 years do Americans of good will say enough already? If the #SpecialCounsel had collusion don’t you think we would have heard it by now? This is history’s longest running smear job. Free @realDonaldTrump Reflect. Negotiate. Open the government.”

BuzzFeed’s report, which was released online Thursday, alleges that Trump told Michael Cohen — his personal attorney — to lie to Congress about a Trump Tower project in Moscow. The president has repeatedly denied having any business dealings with the Russians.

Special counsel Robert Mueller’s office released a statement on Friday night, disputing what was reported.

“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,” wrote special counsel spokesman Peter Carr.

The outlet’s editor-in-chief, Ben Smith, later issued his own statement — saying he and everyone else at BuzzFeed “stand by our reporting and the sources who informed it.”

“We urge the Special Counsel to make clear what he’s disputing,” Smith said.
