President Donald Trump and his team continued their unprecedented attempts to delegitimize and blacklist CNN by refusing to have a representative appear on CNN’s Sunday political talk show, State of the Union, while booking appearances on the other major political talk shows on ABC, CBS, NBC, and Fox Broadcasting Co.

At the top of the January 22 edition of CNN’s State of the Union, host Jake Tapper said that his show “asked the Trump White House for a member of the new administration to join us this morning, but they declined.” Members of Trump’s team including White House Chief of Staff Reince Priebus and counselor to the president Kellyanne Conway, however, made appearances on the other major Sunday political talk shows: This Week on ABC, Face The Nation on CBS, Meet the Press on NBC, and Fox News Sunday on Fox Broadcasting Co. Trump and his team have a long history of blacklisting reporters from events, most notably when Trump revoked The Washington Post’s press credentials during the Republican primaries.

The Trump team’s presumed blackout of CNN comes after escalating attempts to delegitimize the network, brand it as “fake news,” and avoid questions from CNN reporters. During Trump’s first press conference as president-elect on January 11, Trump refused to take a question from CNN senior White House correspondent Jim Acosta, calling his network “fake news” and “terrible.” Following the event, White House Press Secretary Sean Spicer admitted to threatening to remove Acosta from the press conference and later demanded an apology. Trump ally and Fox News contributor Newt Gingrich responded to the incident by asserting that Trump should use the altercation to “shrink and isolate” CNN and eventually “close down the elite press.” Acosta and his colleagues from across the media condemned Trump’s treatment of CNN.

On January 12, Trump doubled down on his attacks against the network, claiming on Twitter that CNN “is in a total meltdown with their FAKE NEWS” and that its “credibility will soon be gone.” Trump also pre-emptively attacked a CNN report on his daughter Ivanka, tweeting that CNN “of all places, is doing a Special Report on my daughter, Ivanka. Considering it is CNN, can’t imagine it will be great!”

The Trump team’s refusal to appear on CNN came one day after it declined to air the live feed of Spicer’s first press conference after the inauguration, where Spicer blatantly lied about the size of inauguration crowds. According to Variety’s Brian Steinberg, “CNN’s refusal to take the live feed suggests executives there are reluctant to put false statements on air, and, what’s more, do not think the new White House press representative is entirely credible.” From the January 21 report:

“CNN’s decision to not air the press conference live illustrates a recognition that the role of the press must be different under Trump. When the White House holds press briefings to promote demonstrably false information and refuses to take questions, then press ‘access’ becomes meaningless at best and complicit at worst,” said Danna Young, an associate professor at the University of Delaware who studies politics and the media. “Democracy works best when journalists have access to the executive branch, of course. But that holds true if and only if that access leads to verifiable, accurate information. The decision on behalf of CNN to wait and verify before airing it live suggests that the media are adapting quickly to this new era.” To be certain, news outlets routinely make decisions about whether to air press events live, usually based on projections about news value. But this press conference, held just a day after the President’s inauguration, would have been a hot prospect for a cable-news outlet, and could have sparked hours of debate and follow-up on CNN’s schedule. In an unusual and aggressive maneuver, CNN aired its regular weekday lineup this Saturday, underscoring heavy interest in breaking news of a series of massive protests by women across the nation in response to Trump’s presidency as well as the new President’s first few days in office.

UPDATE: After an entire week of Trump officials not appearing on CNN, Politico quoted a White House official admitting to a “ban” of CNN by the Trump administration. The official claimed “the ban is not permanent,” but gave no details on why the ban was put in place or when it may be lifted.
