Academics, scholars, and activists Historian
Mark Bray, who has studied the antifa movement, stated in 2017 that "[g]iven the historical and current threat that white supremacist and fascist groups pose, it's clear to me that organized, collective self-defense is not only a legitimate response, but lamentably an all-too-necessary response to this threat on too many occasions." In 2017, Alexander Reid Ross, a lecturer in geography and an author on the contemporary right, argued that antifa groups represented "one of the best models for channeling the popular reflexes and spontaneous movements towards confronting fascism in organized and focused ways." In 2017, historian and
Dissent magazine editor
Michael Kazin wrote that "[n]on-leftists often see the left as a disruptive, lawless force. Violence tends to confirm that view." In 2017, veteran radical activist
Noam Chomsky described antifa as "a major gift to the right", arguing that "the movement was self-destructive and constituted a tiny faction on the periphery of the left."
Civil rights organizations In 2020, the ADL said that while there have been hundreds of murders by far-right groups in the last few decades, there has only been
one suspected antifa-related murder. When Trump threatened to designate antifa as a domestic terrorist organization in 2020, the
Southern Poverty Law Center (SPLC), called this dangerous and a threat to civil liberties. The SPLC also reported that antifa members "have been involved in skirmishes and property crimes, 'but the threat of lethal violence pales in comparison to that posed by far-right extremists. This assessment was replaced with one in 2019 which states that "Antifa is a movement that focuses on issues involving racism, sexism, and anti-Semitism, as well as other perceived injustices. The majority of Antifa members do not promote or endorse violence; however, the movement consists of anarchist extremists and other individuals who seek to carry out acts of violence in order to forward their respective agendas." In September 2017,
Politico obtained confidential documents and interviews indicating that the
Department of Homeland Security (DHS) and the
Federal Bureau of Investigation (FBI) believed that "anarchist extremists" were the primary instigators of violence at public rallies against a range of targets in April 2016. testified to the
Senate Judiciary Committee that the agency "considers antifa more of an ideology than an organization" which was later reiterated the same year in a September 17 remark to lawmakers. According to the
Associated Press, Wray "did not dispute that antifa activists were a serious concern", stating that antifa was a "real thing" and that the FBI had undertaken "any number of properly predicated investigations into what we would describe as violent anarchist extremists", including into individuals who identify with antifa, whom the FBI identified as "a movement or an ideology" rather than as "a group or an organization".
Members of Congress On August 29, 2017,
Nancy Pelosi, then
House Minority Leader for the
Democratic Party, condemned the violence of antifa activists in Berkeley. In June 2020, Republican Senator
Tom Cotton advocated using military force to quell nationwide
protests against police brutality and racism, calling for the
101st Airborne Division to be deployed to combat what he called "Antifa terrorists". Cruz accused "Antifa protesters" of "organizing these acts of terror". In September 2020, Democratic Party presidential candidate
Joe Biden also condemned antifa violent actions, having already condemned violence across the political spectrum and expressed his support for peaceful protests.
Trump administration First presidency (2017–2021) In August 2017, a petition was lodged with the White House petitioning system
We the People calling upon President
Donald Trump to formally classify "AntiFa" as terrorist. The White House responded in 2018 that federal law does not have a mechanism for formally designating domestic terrorist organizations. The writer of the petition later stated he had created it to "bring our broken right side together" and to "prop up antifa as a punching bag".
Politico interviewed unidentified law enforcement officials who noted a rise in activity since the beginning of the Trump administration, particularly a rise in recruitment and on the part of the far right as well since the Charlottesville
Unite the Right rally. One internal assessment acknowledged an inability to penetrate the groups' "diffuse and decentralized organizational structure". By 2017, the FBI and the DHS reported that they were monitoring suspicious antifa activity in relation to terrorism. In May and June 2020, during the nationwide
George Floyd protests following
Floyd's murder, Attorney General
William Barr blamed the violence on "anarchic and far left extremist groups using Antifa-like tactics", and described the actions of "Antifa and other similar groups" as "domestic terrorism", echoing similar statements by National Security Advisor
Robert C. O'Brien. In
Twitter posts and other statements, Trump blamed "ANTIFA and the Radical Left" for violence, and repeatedly pledged that the federal government would designate antifa as a "Terrorist Organization". However, the president lacks the authority to do so because under existing law the federal government may designate only
foreign organizations as terrorist and antifa is a loosely associated movement rather than a specific organization. Legal experts, among others, believe that designating antifa as a terrorist group would be unconstitutional, raising
First Amendment and
due process issues. In 2020, historian Mark Bray wrote that antifa cannot be designated as a terrorist organization because "[t]he groups are loosely organized, and they aren't large enough to cause everything Trump blames them for." Two days later, Barr claimed that "[w]e have evidence that antifa and other similar extremist groups, as well as actors of a variety of different political persuasions have been involved in instigating and participating in the violent activity." However, the Trump administration has provided no evidence for its claims According to Bray, while "confident that some members of antifa groups have participated in a variety of forms of resistance" during the protests, it is "impossible to ascertain the exact number of people who belong to antifa groups." As of June 9, 2020, none of the 51 people facing federal charges were alleged to have links to antifa. As of September 16, 2020, no antifa or left-wing group has been charged in connection with the civil unrest. In an August 2020 interview, Trump asserted "people that are in the dark shadows" control his Democratic presidential opponent
Joe Biden and then claimed that "we had somebody get on a plane from a certain city this weekend, and in the plane it was almost completely loaded with thugs, wearing these dark uniforms, black uniforms, with gear and this and that", adding that "they're people that are on the streets. They're people that are controlling the streets." Antifa activists commonly dress in black. Trump's remarks were similar to false social media rumors during preceding months that planes and buses full of antifa gangs were preparing to invade communities, allegedly funded by
George Soros. Two days after Trump's remarks, Barr asserted he knew antifa activists "are flying around the country" and "we are following them". However, there is no evidence of any such flight.
Brian Murphy, who was the
Under Secretary of Homeland Security for Intelligence and Analysis until August 2020, asserted that DHS secretary
Chad Wolf and his deputy
Ken Cuccinelli instructed him "to modify intelligence assessments to ensure they matched up with the public comments by President Trump on the subject of ANTIFA and 'anarchist' groups." On September 18, 2020, Trump publicly criticized FBI Director
Christopher A. Wray and hinted that he could fire him over Wray's testimony about antifa and
Russian interference in the 2020 United States elections. On September 25, 2020, the
Trump campaign released details of a "Platinum Plan for Black America", under which Antifa and the
Ku Klux Klan would be prosecuted as terrorist organizations.
Second presidency (2025–present) On September 17, 2025, Trump announced plans to designate antifa as a "major terrorist organization". The announcement came a week after the
assassination of Charlie Kirk. Much like his attempt to do so in 2020, it is unclear how this would happen as the president lacks the authority to designate antifa as a terrorist organization. Legal experts once again expressed concerns about the first amendment and political suppression should it happen while others questioned whether such a designation would even have any impact. According to
Mary B. McCord, the acting head of the DOJ's national security division during the Obama administration and the first Trump administration, "Trump can declare whatever he wants to declare, but there is no legal authority to actually designate a domestic group as a terrorist organization even assuming that antifa is an organization and not just an ideology. That means [Trump] declaring this has no legal impact. Certainly it does not trigger criminal terrorism charges, like providing material support to a foreign terrorist organization." On September 22, Trump filed an
executive order intended to designate antifa as a
domestic terrorist organization, with the lack of a formal legal mechanism to do so. According to the executive order, the administration will "investigate, disrupt, and dismantle" individuals and groups associated with, or providing material support, to antifa. This resulted in a surge on white supremacist social media channels, urging them to target specific people and perceived antifa members. Legal experts questioned the move, citing the lack of any federal authority to designate domestic terror groups, the fact that antifa is a movement rather than an organization, and the first-amendment concerns raised by using federal power against a domestic movement. == Hoaxes and conspiracy theories ==
