Trump designated antifa a terrorist group after the assassination of Charlie Kirk last month, where the suspected assassin inscribed antifa slogans on his bullet shell casings. The network has organized violent attacks against law enforcement and conservative figures since the founding of the first U.S. antifa chapter in Portland, Oregon, in 2007.

The network became best known after Trump took office for the first time, staging violent riots in Washington, D.C., the day he was inaugurated, in Berkeley, California, and Charlottesville, Virginia, in 2017, and across the country during the George Floyd riots of 2020.

WHAT IS ANTIFA AND HOW DOES TERRORIST DESIGNATION AFFECT LEFT-WING NETWORK?

Antifa, short for Antifascist Action, is a radical left-wing militant network that endorses terrorist tactics in order to combat fascism, which translates to any political group or figures opposed to its lofty, sometimes Marxist aims. Though antifa and its supporters have attempted to deflect attention and investigation by claiming it is a movement and not an organization, multiple investigations into local chapters and new research have found a rigid command-and-control structure, a structured onboarding and training process, and strict ideological training courses.
