Which local antifa or anarchist groups have publicly admitted to organizing intercity protest travel or mutual aid for demonstrations since 2016?

1. Rose City Antifa and Portland networks: local organizing that reached other cities

Rose City Antifa, the long‑standing Portland group cited by multiple analysts, has been publicly active in organizing protests and coordinating with other Pacific Northwest affinity groups, and Portland’s anarchist milieu has served as a hub for sending activists and sharing tactical and mutual‑aid resources with demonstrations in other cities ^{[2] [1]}.

2. “It’s Going Down” and the role of anarchist media in coordinating travel and mutual aid

“It’s Going Down,” the large anarchist news and organizing site, has published calls, logistics, and mutual‑aid/bail solidarity appeals that facilitated intercity movement and support for demonstrations—acting as a public conduit for coordination rather than a hierarchical organizer ^{[3] [4]}.

3. Youth Liberation Front and coordinated multi‑city actions (#J25 and beyond)

Researchers and reporting identified the Youth Liberation Front and related autonomous networks as organizers of synchronized actions across more than 20 cities (the #J25 call), which included public statements, logistical messaging and mutual‑aid framing—evidence that some local groups and networks publicly claimed responsibility for multi‑city mobilizations ^[3].

4. Named local chapters that have publicly coordinated regionally (NYC Antifa, Anti‑Fascist Sacramento, New Jersey chapters)

Local groups such as NYC Antifa and Anti‑Fascist Sacramento are repeatedly referenced in reporting as organized local chapters that coordinated deployments and participated in protests beyond their home city, and New Jersey reporting identified North Jersey Antifa, South Jersey Antifa and HubCity Antifa New Brunswick as loosely organized chapters that coordinated regionally and have participated in demonstrations in nearby metropolitan areas ^{[1] [5]}.

5. Support functions: bail funds, medics, and “community defense” groups

Law‑enforcement and intelligence reporting has singled out anarchist networks that explicitly prepared bail funds, recruited medics, and organized medical teams in advance of protests—showing public and semi‑public admission of mutual‑aid roles by certain anarchist organizers rather than covert logistic cells (New York JTTF intelligence cited in reporting; p1_s2). Similarly, the Puget Sound John Brown Gun Club publicly framed itself as a community defense organization and linked anti‑fascist organizing to local mutual‑aid and defensive training ^[1].

6. Limits, ambiguity, and the decentralized reality

Multiple expert and government sources emphasize that “antifa” is an ideology and a loosely connected set of local actors rather than a single organization with national headquarters; as a result, public admissions tend to come from individual city groups, online platforms, and autonomous affinity networks rather than formal national admissions—creating inherent limits on attributing centralized coordination ^{[6] [2] [4]}.

7. What the evidence does and does not show

Reporting documents that specific local groups and networks—Rose City Antifa, NYC Antifa, Anti‑Fascist Sacramento, New Jersey Antifa chapters, Antifascist Action‑Nebraska, Youth Liberation Front, It’s Going Down and allied community defense groups like Puget Sound John Brown Gun Club—have publicly organized, solicited mutual aid, or called for coordinated multi‑city actions since 2016; however, the evidence does not support a claim of a single, hierarchical national “antifa” organization, and much coordination is mediated through public postings and decentralized networks rather than formal structure ^{[5] [2] [3] [1] [4] [7]}.
