About CNN (Online News)

CNN (Online News) is featured on the AllSides Media Bias Chart™.

CNN (Online News) is a news media source with an AllSides Media Bias Rating™ of Left.

From 2017 to 2021, the bias of CNN's web news shifted significantly, from Center, to Lean Left, to Left. CNN, its employees, and its content are commonly associated with liberal media bias by voices across the political spectrum in the public discourse.

NOTE: This rating is not for CNN's TV/broadcast content, nor its opinion/editorial content. This bias rating reflects the online, written news content available on only. AllSides does not rate broadcast content for any outlet. We also provide a separate media bias rating for CNN's Opinion/Editorial content here.

We split our bias ratings for CNN Web News and CNN Opinion/Editorial on December 21st, 2017, because they were significantly different; read our explanation here. In January 2021, we determined the bias of CNN's news content and editorial content matched, and were both rated Left.

What a "Left" Rating Means

Sources with an AllSides Media Bias Rating of Left display media bias in ways that strongly align with liberal, progressive, or left-wing thought and/or policy agendas. This is our most liberal rating on the political spectrum.

CNN Fact Check Also Has Left Bias: July 2021 Editorial Review

CNN’s fact check section has a Left bias, according to a July 2021 Small Group Editorial Review by AllSides editors on the left, center, and right.

CNN Moved from Lean Left to Left Following Nov. 2020 Blind Bias Survey

After analyzing the results of our November 2020 Blind Bias Survey, in which 2,285 people across the political spectrum blindly rated CNN's content, AllSides moved CNN's Media Bias Rating™ from Lean Left to Left. We officially shifted CNN's bias rated to left on Jan. 15, 2021.

On average, people who self-reported that they are on the left rated CNN as being between Lean Left and Left; people in the center and on the right found CNN on average to be Left. The average rating from people across the political spectrum was Left.

For this survey, AllSides collected two types of content from CNN's website: top headlines from two different days at the same time of day, and top stories CNN ran around two major national news stories. Stories and headlines were stripped of branding and any information that would allow participants to identify the outlet. Participants were asked to rate the bias of CNN on a scale of Left, Lean Left, Center, Lean Right, and Right.

After analyzing the results of this survey, members of the AllSides team conducted some independent reviews of CNN's content, and decided to move the outlet's rating to Left.

During our independent reviews, team members on the left, center and right noted a lot of sensationalism in CNN's news reporting. One team member with a Center bias said, "CNN uses proper source attribution and good hyperlinks, and often has clear, accurate labels for content. However, its homepage is dominated by anti-Trump/anti-GOP narratives and features few to zero anti-left/anti-Democrat narratives. The reports themselves are often skewed by a lack of right-leaning sources, biased/subjective language, or omission of facts that may, if included, counter a left-leaning point of view."

We found CNN's fact-checking section was very skewed toward an anti-Donald Trump/anti-GOP focus, and that the outlet didn't focus nearly as much on fact checking Democrats or Joe Biden — or really anything except President Donald Trump.

CNN Moved from Center to Lean Left in March 2018 Editorial Review

After conducting deep editorial analysis and analyzing user feedback, on March 27th, 2018, AllSides moved the Media Bias Rating™ for CNN Web News from Center to Lean Left. More details as to why we made the change can be found in our March 2018 blog post on the matter, as well as below.

After years of receiving feedback from AllSides users that our media bias rating of CNN Web News as Center was incorrect, we conducted an extensive editorial review in March 2018, after which we decided to move CNN Web News to a Lean Left rating.

For our review of CNN Web News, the entire AllSides team read CNN’s homepage and politics page every day for a week and compared it to other Center and Lean Left sources. We looked at the stories CNN chose to cover as well as the prominence certain stories held over others.

We found CNN Web News has a tendency to include a lot of Opinion and Analysis without labeling it clearly as such until afterreaders clicked through to the full article. This means CNN displayed Opinion-level content alongside hard news on the homepage, making it look like the Opinion pieces are objective, fact-based news.

We also found that there were Left-leaning and Center articles featured on CNN, but the outlet never published a Right-leaning article. (Note that a Center rating is assigned if we see a balance of biases being represented, which is not the case with CNN.)

CNN Rated Center in Jan. 2013 and Oct. 2013 Blind Bias Surveys, UCLA Study

The results from AllSides' January 2013 and October 2013 blind surveys, as well as data from a 2005 UCLA study of media bias all rated CNN as Center. However, the scores in both of the blind surveys were on the border of Center, leaning towards Left.

Additional Information

Third-Party Accusations of Bias

In October 2019, Project Veritas published videos claiming to reveal the network's anti-Trump bias.

In January 2020, CNN faced accusations of bias over its moderation of a 2020 presidential debate between Democratic candidates.

In 2021, as former New York Gov. Andrew Cuomo faced widespread criticism over sexual harassment allegations and a cover-up of COVID-19 deaths in nursing homes, CNN took criticism. Chris Cuomo, a prime-time CNN television host and brother of Andrew, was accused of avoiding coverage of his brother's scandals after hosting him on his show for playful TV segments throughout the COVID-19 pandemic. The network faced similar allegations of avoiding negative coverage of Andrew.

Political Leanings of CNN's Audience as of 2014

According to the 2014 Pew Research Study, Where News Audiences Fit on the Political Spectrum, 44% of CNN’s audience holds political values to the political left or left-of-center. About 17% of CNN's audience holds right or right-of-center political values (compared with 38% of all respondents to the survey). Roughly 40% of CNN's audience is considered to have mixed or center-aligned political values (compared with 36% of all respondents to the survey).

Is CNN Fake News?

President Donald Trump and others have accused CNN of being fake news. Fake news can be defined in many ways, and can refer to either overtly false information, or information that is biased or manipulative in some way. AllSides explored whether CNN is fake news on the blog in May 2019.
