The timeline below shows the percentage of monthly airtime across CNN, MSNBC and Fox News over the past decade mentioning immigration. Coverage largely faded across all three channels in late 2019 and began to climb sharply on Fox News in January 2021. As of mid-March 2021 Fox News is devoting more attention to the topic than it has in any month of the past decade except January 2019. In stark contrast, CNN and MSNBC are barely mentioning the topic and have only this month begun to devote any real coverage to it.
The timeline belows shows the percentage of airtime describing the immigration situation as a "crisis," showing that since mid-2014 immigration has been a "crisis" only on Fox.
