This bill, titled the Domestic Terrorism Prevention Act of 2025, aims to combat domestic terrorism by establishing dedicated offices within key federal agencies. It authorizes a Domestic Terrorism Unit in the Department of Homeland Security, a Domestic Terrorism Office in the Department of Justice, and a Domestic Terrorism Section within the Federal Bureau of Investigation. These offices are tasked with monitoring, analyzing, investigating, and prosecuting domestic terrorism, with a specific focus on ensuring compliance with civil rights and civil liberties laws and requiring annual anti-bias training for staff. These offices are authorized for a period of 10 years. The legislation mandates that these newly authorized offices submit biannual joint reports to Congress for a decade. These reports must include an assessment of the domestic terrorism threat posed by White supremacists and neo-Nazis , including their infiltration of law enforcement and uniformed services. Furthermore, the reports require a quantitative analysis of domestic terrorism incidents, investigations, arrests, indictments, prosecutions, and convictions, with specific categories for White supremacist-related activities. All unclassified portions of these reports are to be made publicly available. To enhance coordination, the bill authorizes a Domestic Terrorism Executive Committee within the Department of Justice, comprising representatives from various federal entities. This Committee will meet regularly to promote information sharing among law enforcement and convene local forums to build trust and strengthen alliances with community groups. Additionally, the bill requires the review and enhancement of anti-terrorism training programs for federal, state, local, and tribal law enforcement, ensuring they include resources for understanding, detecting, and investigating domestic terrorism, particularly White supremacist and neo-Nazi infiltration. An interagency task force, involving the Attorney General, FBI Director, and Secretaries of Homeland Security and Defense, is to be established to analyze and combat White supremacist and neo-Nazi infiltration of the uniformed services and federal law enforcement agencies. The bill also strengthens federal support for addressing hate crime incidents with a nexus to domestic terrorism, including assigning special agents or hate crime liaisons to FBI field offices. Crucially, the legislation includes a rule of construction clarifying that nothing in the Act may be construed to infringe upon First Amendment rights or other applicable federal laws.
