Have any US political parties been officially designated as terrorist groups?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
No U.S. political party has been officially designated as a terrorist organization under U.S. law; federal statutory and executive designation regimes apply to foreign organizations or to legal authorities that do not create a formal “domestic terrorist organization” list with clear statutory penalties, and recent public claims or executive actions targeting movements such as “antifa” are contested and legally complicated [1] [2] [3] [4].
1. Legal architecture: how the United States designates terrorist organizations
The principal statutory pathway for labeling groups as “terrorist” at the federal level is the Foreign Terrorist Organization (FTO) process run by the Secretary of State under Section 219 of the Immigration and Nationality Act, which by definition applies only to foreign organizations and carries immigration and criminal-support consequences [1] [2]. Separately, Executive Order 13224 and Treasury sanctions lists allow the U.S. government to block assets and disrupt financing for designated foreign terrorists and financiers, instruments designed for external threats rather than internal political parties [5] [2]. The National Counterterrorism Center and State Department frameworks also distinguish state sponsors, foreign groups, and sanctions regimes—none of which create a mechanism to formally designate a domestic political party as a terrorist organization under those authorities [6] [2].
2. Domestic designations — authority, limits and legal controversies
There is no settled federal mechanism that mirrors the FTO process for domestic organizations; legal scholars and civil liberties groups warn that extending foreign-designation tools domestically would raise severe First Amendment and due-process problems and could criminalize broad political activity [4]. Administration memoranda and taskings that direct agencies to identify and disrupt “domestic terrorist” actors have blurred lines between criminal prosecution and political expression, but reporting shows those efforts do not equal the clear, statutory FTO labeling process and often leave the public uncertain who, if anyone, is formally listed [7] [4].
3. Recent high-profile moves and public claims about political parties and movements
In recent years the White House and administration officials have sought to brand or target movements—most prominently “antifa”—with terrorism language: a White House statement in 2025 claimed to designate antifa as a “domestic terrorist organization,” and the administration has pursued designations and sanctions against overseas groups described as violent antifa affiliates [8] [9]. At the same time, senior aides and officials have publicly suggested partisan labels—such as claims that the Democratic Party is a “domestic extremist organization”—but those are political assertions, not statutory designations and have been reported and critiqued as rhetoric with chilling implications [3].
4. What the evidence shows about U.S. political parties specifically
No factual record in the reviewed reporting indicates that any U.S. political party—Democratic, Republican, or any third party—has been officially designated as a terrorist organization under the FTO process or any other statutory U.S. foreign-terrorism regime, and scholarly and legal sources emphasize that existing formal designations are for foreign entities or specific named groups rather than U.S. parties [1] [2]. Where the administration has used language or administrative memos to compile lists or target domestic actors, reporting documents that those efforts are opaque, contested, and legally fraught rather than reflecting an established statutory designation of a domestic political party [7] [4].
5. The stakes: law, politics, and confusion ahead
The distinction between rhetorical labeling, executive directives aimed at disrupting violence, and lawful statutory designations is consequential: FTO and SDGT labels trigger clear penalties like asset-blocking and material-support crimes for foreign entities [5] [2], while attempts to apply similar frameworks domestically would raise constitutional challenges and practical uncertainty about who is targeted and how enforcement would proceed [4] [7]. Reporting shows the U.S. continues to add foreign groups to terrorism lists and to use sanctions tools abroad, but there is no authoritative source in the material provided that supports an official designation of any American political party as a terrorist organization [2] [1].
