How direct is the connection between what President Donald Trump communicated to his supporters and their actions in laying siege to the U.S. Capitol? Videos recorded by many individuals over the course of the day provide some answers. A portion of these videos have not been seen widely before, including video footage largely from the platform Parler showing how the crowd reacted in real time to some of the most potent lines in Trump’s speech at the Ellipse. The videos, along with other information in the public record, provide strong evidence of a causal link between Trump’s messages to his supporters and their dangerous, illegal conduct. The collection of videos, viewed chronologically, also shows the ways in which Trump placed the life of Vice President Mike Pence, among others, in grave danger.
