U.S. intelligence officials have corroborated certain communications included in the "Russia dossier" reported in January.
Both President-elect Donald Trump and President Barack Obama were briefed on the existence of the 35-page dossier, which made unverified allegations about Trump's personal and financial dealings with Russia, in early January.
The details confirmed by agents do not relate directly to Trump, rather to conversations between foreign nationals, which took place on the dates mentioned in the dossier, CNN reports.
"We continue to be disgusted by CNN's fake news reporting," White House Press Secretary Sean Spicer said in response to the latest information, CNN reports.
He called the network back later with a further comment.
"This is more fake news," Spicer added. "It is about time CNN focused on the success the President has had bringing back jobs, protecting the nation, and strengthening relationships with Japan and other nations. The President won the election because of his vision and message for the nation."
The anonymous sources who spoke to CNN emphasized that none of "the more salacious things" about Trump contained in the dossier had been verified. A former British intelligence operative, Christopher Steel, reportedly prepared the document for Trump's opponents during the election campaign.
BuzzFeed and other online outlets published the dossier in full, notes the Independent. However, CNN, which broke the story, chose not to publish some of the unverified allegations.
Trump attacked the dossier on Twitter in January.
"I win an election easily, a great 'movement' is verified, and crooked opponents try to belittle our victory with FAKE NEWS. A sorry state!" Trump tweeted.
"Intelligence agencies should never have allowed this fake news to 'leak' into the public," he added. "One last shot at me. Are we living in Nazi Germany?"
Trump also remarked on the dossier at his only press conference as President-elect.
"It's all fake news," he said, according to CNN. "It's phony stuff. It didn't happen."
