President-elect Donald Trump's incoming press secretary blasted BuzzFeed for releasing an unsubstantiated, unconfirmed report regarding Trump and ties to Russia.

"It's frankly outrageous and highly irresponsible for a left-wing blog that was openly hostile towards the President elects campaign, to drop highly salacious and flat out false information on the internet just days before he takes the oath of office," Spicer said.

"According to BuzzFeed's own editor, there are some serious reasons to doubt the allegations in the report," Spicer added. The executive editor of the New York Times dismissed the report. (RELATED: Morning Joe Attacks BuzzFeed, CNN Report: 'There's No Story Here')

"The fact that BuzzFeed and CNN made the decision to run with this unsubstantiated claim is a sad and pathetic attempt to get clicks," Spicer said, adding that the New York Times dismissed the report due to a lack of evidence.

"The report was not an intelligence report, plain and simple," the incoming White House press secretary asserted.

Vice President-elect Mike Pence and Trump also railed against specific members of the media for reporting the unverified report following Spicer's presentation.

BuzzFeed and the Republican National Committee, where Spicer was the communications director and chief strategist, signed an agreement to "spend a significant amount on political advertisements slated to run during the Fall election cycle," in April 2016, according to Politico. BuzzFeed cancelled the $1.3 million advertising contract in June, citing the nomination of Trump as the reason.

Trump held his first press conference since his election victory Wednesday morning in Manhattan.
