The "No Kings" protests in every state may have been the biggest day of demonstrations in American history, a data analyst has suggested. Based on hundreds of crowd-sourced records of No Kings Day event turnout, and extrapolating for the cities where we don't have data yet, it looks like roughly 4-6 million people protested Trump across the U.S. yesterday, dependent data journalist G Elliott posted to X Sunday. For reference, that's between 1 and 2 percent of the total population of the United States.
