Presidential Authority and the Legitimation of Far-Right News

What position do far-right news outlets occupy in contemporary U.S. politics, and how did Trump use the power of the presidency to contribute to their rise among Republican legislators and mainstream American media? We posit that Trump's position as president, in conjunction with his populist communication style that favored far-right outlets, contributed to the legitimation of such outlets. We first analyze Trump's tweets during his presidency (January 2017-January 2021) mentioning three far-right outlets (One America News Network, Newsmax, and Breitbart), conceptualizing these messages as authority signals that symbolically lend legitimacy to the media sources. We then provide rich descriptive information regarding subsequent mentions of the far-right outlets in four national mainstream newspapers as well as appearances by GOP (Republican) members of Congress in the far-right outlets. We find significant and positive correlations between Trump's tweets and mainstream media coverage of One America News Network (OANN) and Newsmax, and significant and positive correlations between Trump's tweets and GOP Congressional interviews on OANN and Newsmax. Together, these results represent an example of presidential authority signals that bolster far-right outlets and aid in their legitimization among legislators and the mainstream press. The findings shed light on the role of political leaders in the recent mainstreaming of the far-right across many democratic countries.
