Matthew G. Olsen, the head of the Justice Department’s National Security Division, announced the unit in his opening remarks before the Senate Judiciary Committee, noting that the number of FBI investigations of suspected domestic violent extremists — those accused of planning or committing crimes in the name of domestic political goals — had more than doubled since the spring of 2020.
Domestic terrorism or homegrown terrorism is a form of terrorism in which victims “within a country are targeted by a perpetrator with the same citizenship” as the victims. There are many definitions of terrorism, and none of them are universally accepted.
Domestic Terrorism for the FBI’s purposes is referenced in U.S. Code at 18 U.S.C. 2331(5),
and is defined as activities:
• Involving acts dangerous to human life that are a violation of the criminal laws of the United
States or of any State;
• Appearing to be intended to:
o Intimidate or coerce a civilian population;
o Influence the policy of government by intimidation or coercion; or
o Affect the conduct of a government by mass destruction, assassination or kidnapping;
• Occurring primarily within the territorial jurisdiction of the United States.
This is a definitional statute, not a charging statute. We talk about the threat these actors pose as
Domestic Terrorism threats, but each of the FBI’s threat categories, described in further detail below,
uses the words “violent extremism” because the underlying ideology itself and the advocacy of such
beliefs is not prohibited by US law.
In using the term Domestic Terrorism, DHS looks to the Homeland Security Act definition of
terrorism, 6 U.S.C. 101(18), which is substantially similar but not identical to the title 18
definition. That provision defines terrorism as any activity that:
• Involves an act that:
o Is dangerous to human life or potentially destructive of critical infrastructure or key
o Is a violation of the criminal laws of the United States or of any State or other
subdivision of the United States; and
• Appears to be intended:
o To intimidate or coerce a civilian population;
o To influence the policy of a government by intimidation or coercion; or
o To affect the conduct of a government by mass destruction, assassination, or
In this vein, the FBI and DHS use the term Domestic Violent Extremist (DVE) to describe an
individual based and operating primarily within the territorial jurisdiction of the United States
who seeks to further their ideological goals wholly or in part through unlawful acts of force or
violence.1 It is important to remember that the mere advocacy of ideological positions and/or the
use of strong rhetoric does not constitute violent extremism, and in some cases direct or specific
threats of violence must be present to constitute a violation of federal law.
The US Government, including the FBI and DHS, continually reviews and evaluates intelligence
to ensure it is appropriately identifying and categorizing a variety of national security threats to
the Homeland. As part of this continual internal review, the FBI and DHS reconfigure broad threat
categories as the threats evolve. While categories help the FBI better understand the criminal
actors we pursue, we recognize actors’ motivations vary, are nuanced, and sometimes are derived
from a blend of ideologies. The categories also inform the intelligence and prevention efforts of
DHS. Currently, the US Government broadly divides the DT threat among the following threat
Racially or Ethnically Motivated Violent Extremism: This threat encompasses the potentially
unlawful use or threat of force or violence in furtherance of ideological agendas derived from bias,
often related to race or ethnicity, held by the actor against others or a given population group.
Racially or Ethnically Motivated Violent Extremists purport to use both political and religious
justifications to support their racially- or ethnically-based ideological objectives and criminal
Anti-Government or Anti-Authority Violent Extremism: This threat encompasses the
potentially unlawful use or threat of force or violence in furtherance of ideological agendas,
derived from anti-government or anti-authority sentiment, including opposition to perceived
economic, social, or racial hierarchies, or perceived government overreach, negligence, or
Animal Rights/Environmental Violent Extremism: This threat encompasses the potentially
unlawful use or threat of force or violence in furtherance of ideological agendas by those seeking
to end or mitigate perceived cruelty, harm, or exploitation of animals and/or the perceived
exploitation or destruction of natural resources and the environment.
Abortion-Related Violent Extremism: This threat encompasses the potentially unlawful use or
threat of force or violence in furtherance of ideological agendas relating to abortion, including
individuals who advocate for violence in support of either pro-life or pro-choice beliefs.
All Other Domestic Terrorism Threats: This category encompasses threats involving the
potentially unlawful use or threat of force or violence in furtherance of ideological agendas which
are not otherwise defined under or primarily motivated by one of the other Domestic Terrorism
threat categories. Such agendas could flow from, but are not limited to, a combination of personal
grievances and beliefs, including those described in the other Domestic Terrorism threat
categories. Some actors in this category may also carry bias related to religion, gender, or sexual
1 The DHS Office of Intelligence & Analysis (I&A) does so in accordance with its Attorney General-approved
Intelligence Oversight Guidelines (Policy No. IA-1000). I&A uses the term “domestic terrorist,” defined in those
guidelines, interchangeably with “domestic violent extremist” to describe such an actor.
The FBI recognizes a Domestic Terrorism Incident as an ideologically-driven criminal act,
including threats or acts of violence made to specific victims, made in furtherance of a domestic
ideological goal, that has occurred and can be confirmed. A single incident may be comprised of a
scheme or a serial criminal or violent activity conducted by the same perpetrator(s) using the same
The FBI recognizes a Domestic Terrorism Plot as a combination of criminal activity and planning
that collectively reflect steps toward criminal action in furtherance of a domestic ideological goal.
Disrupted Domestic Terrorism Plots are plots which, in the FBI’s assessment, absent law
enforcement intervention could have resulted in a Domestic Terrorism incident.
The FBI makes every effort to proactively document lethal and non-lethal Domestic Terrorism
incidents, but it is important to note there is no mandatory incident reporting requirement that
mandates state and local law enforcement agencies to report criminal activity that appears
to be ideologically-motivated consistent with the DT threat categories previously defined.
This makes it impossible for the FBI to ensure we have complete and comprehensive knowledge
of any and all incidents of this nature that may take place across the United States. For example, if
the FBI does not receive notification from state and local officials of an ideologically-motivated
criminal act, especially one that did not result in injury or loss of life, the FBI may not know to
include that incident in our records.
