"AI Overview

Analyses from government agencies and independent research groups indicate that white supremacists and other right-wing extremists are responsible for the majority of lethal domestic terrorism in the U.S. in recent years.

Dominant threat

Right-wing extremist violence has caused a significant percentage of domestic terrorism deaths since 2001, with some analyses placing the figure as high as 75% to 80%. White supremacists have been responsible for a large portion of fatalities within right-wing extremist attacks.

Both the Department of Homeland Security and the Federal Bureau of Investigation have identified white supremacist violence as the "most persistent and lethal terrorist threat to the homeland".

White supremacist violence remains a top counterterrorism concern, and data shows it has been more frequent and deadlier than violence from left-wing extremists.

Specific examples of white supremacist violence
Prominent attacks linked to white supremacists include the Oklahoma City bombing (1995), the Charleston church shooting (2015), the Tree of Life synagogue attack (2018), the El Paso Walmart massacre (2019), and the Buffalo mass shooting (2022)."
