A late 2018 analysis by a Wikipedia editor, banned from the site at the time due to criticism of political bias, showed left-wing British outlet the Guardian was the third most-cited news source on the online encyclopedia after the New York Times and the BBC, in many cases to make negative claims about President Donald Trump and other conservatives. Most of the top-cited news sources on Wikipedia are establishment left-leaning news outlets. Conservative outlets are disfavored by Wikipedia editors who cite the site’s standards for “reliable sources” with some outlets, including Breitbart, formally banned.
