On January 17, 2016, the alt-right news site Breitbart found itself under siege: A number of IP addresses were sending a large amount of traffic its way, straining its servers.

With the resurgence of the American left, we wanted to see whether or not any agencies were tracking the 2017 May Day demonstrations. Documents we received from the Department of Homeland Security’s Office of Intelligence and Analysis show that Antifa was specifically targeted and that DHS was sourcing its intelligence from a white supremacist website called “Occidental Dissent.”
