A memo published by the Office of Intelligence and Analysis (OIA), part of the Department of Homeland Security, on August 17th says that violent extremists motivated by ideologies like white supremacy “could quickly mobilize to threaten or engage in violence against election or campaign-related targets in response to perceived partisan and policy-based grievances.”

The memo says that while the OIA aren’t aware of a specific plot to attack the election physically, “open-air, publicly accessible parts of physical election infrastructure,” such as campaign and voter registration events, “would be the most likely flashpoints for potential violence.”
