Black drivers were more likely to be stopped by police after Trump rallies in 2016

In new research, Pauline Grosjean, Federico Masera, and Hasin Yousaf look into how Trump’s 2016 presidential campaign affected police behavior toward Black Americans. They find that that Black drivers were 5.7 percent more likely to be stopped by police after a Trump rally, and that this effect happens immediately after the rally, is specific to Black drivers, lasts for up to 60 days and is not justified by changes in driver behavior.
