Donald Trump has clashed with network before
US President Donald Trump has had his run-ins with the media, but a new move may go even further.
According to Politico, the White House has refused to send its spokespeople or surrogates onto CNN shows.
The publication say this would effectively 'ice out' the network from on-air administration voices.
“We’re sending surrogates to places where we think it makes sense to promote our agenda,” a White House official told the political website - acknowledging that CNN is not such a place.
However it is not thought the so-called 'ban' is permanent.
Comment from CNN was not available at time of publication.
Mr Trump clashed with CNN before during a January press conference, when he accused them of being “fake news”.
"Your organisation's terrible - quiet, quiet. I'm not going to give you a question - you are fake news", he told CNN's senior White House correspondent Jim Acosta.
The incident related to an alleged dossier about Mr Trump that was published by BuzzFeed.
Aspects of this were subsequently covered by CNN, but the network did not publish the full document.
In a statement last month, CNN said its decision "to publish carefully sourced reporting about the operations of our government is vastly different than Buzzfeed’s decision to publish unsubstantiated memos."
It added: "The Trump team knows this. They are using Buzzfeed’s decision to deflect from CNN’s reporting, which has been matched by the other major news organizations.
“We made it clear that we were not publishing any of the details of the 35-page document because we have not corroborated the report’s allegations. Given that members of the Trump transition team have so vocally criticized our reporting, we encourage them to identify, specifically, what they believe to be inaccurate."
