The US saw a resurgence of racial and ethnic turmoil and tensions during Donald Trump’s presidency. This column examines how Trump's 2016 presidential campaign affected police behaviour towards Black Americans, using data on nearly 12 million vehicle stops by the police in 142 counties where Trump held a rally during his campaign. It finds that the probability that a driver stopped by police would be Black increased after a Trump event, and estimates that Trump's rallies may have led to nearly 30,000 additional stops of Black people by the police in the months following his rallies.
