This bill officially designates Antifa as a domestic terrorist organization, based on congressional findings that describe it as a militarist, anarchist enterprise using violence and coordinated efforts to obstruct federal laws and suppress political speech. It mandates all relevant executive branch departments and agencies to utilize their authorities to investigate, disrupt, and dismantle Antifa's illegal operations, specifically targeting terrorist actions and their funding sources.

The legislation directs the National Joint Terrorism Task Force (JTTFs) to establish a comprehensive national strategy to investigate and prosecute individuals and entities involved in political violence and intimidation. This strategy includes probing those who recruit for such violence, as well as institutional and individual funders who aid and abet these criminal acts, including potential violations of the Foreign Agents Registration Act or money laundering.

The bill requires the Attorney General to prosecute all related Federal offenses and issue guidance prioritizing politically motivated terrorist acts like organized doxing campaigns, rioting, and property destruction. It also tasks the Secretary of the Treasury with identifying and disrupting financial networks supporting domestic terrorism and mandates the Commissioner of Internal Revenue to ensure tax-exempt entities are not financing such activities.

Additionally, the legislation instructs Federal law enforcement to question individuals engaged in political violence about organizational and financial sponsorship, prioritizing specific crimes such as assaulting federal officers or conspiracy against rights. It also designates domestic terrorism as a national priority area for the Attorney General and Secretary of Homeland Security, enabling grant programs for law enforcement partners to detect and prevent threats.
