The Trump administration is organizing an international summit focused on countering the left-wing movement antifa and other groups, three sources familiar with the matter said, an effort that reflects changes in the U.S. government's counterterrorism priorities over the past year.
The conference, tentatively planned for June or July, will convene officials from various nations to discuss strategies for addressing antifa and encourage intelligence sharing, said the sources, who requested anonymity as they were not authorized to speak to the media.
President Donald Trump has described antifa as a significant threat to the U.S.
Some counterterrorism experts say it does not exist as a centralized organization, though individuals identifying with antifa have been involved in armed attacks in the U.S.
Among the officials organizing the event is Under Secretary of State for Arms Control and International Security Thomas DiNanno, said two of the people.
In response to requests for comment, spokespeople for the White House and State Department both described antifa as a major security concern for the Trump administration.
"The anarchists, Marxists, and violent extremists of antifa have waged a terror campaign in the United States and across the Western world for decades, carrying out bombings, beatings, shootings, and riots in service of their extreme agenda," said Tommy Pigott, the State Department's principal deputy spokesman.
The planned event has prompted questions among some current and former officials, who say the summit could divert attention as the U.S. faces threats from Iran-sponsored groups linked to the war in the Middle East.
"I am just skeptical that now, with everything going on, when you see the number of plots being put together by Iran and Hezbollah, that there really is a compelling need to spend limited counterterrorism resources on the antifa threat right now," said Michael Jacobson, who was the director of strategy, plans and initiatives for the State Department's Counterterrorism Bureau until 2025. Now, he is a senior fellow at the Washington Institute for the Near East Policy think tank.
A State Department official said the administration had taken "unprecedented steps to combat terrorism worldwide," including many actions against Hezbollah, Hamas, the Yemen-based Houthis and various drug cartels.
Many details of the planned event were unclear, including which countries were invited and would participate.
As of last week, formal invitations for the conference had not yet been sent, two of the people said. The State Department official said no summit date had been set.
It was also unclear whether the event would focus specifically on groups or individuals that self-identify with antifa, or on left-wing groups more broadly. At times, senior administration officials have used the term antifa to refer more broadly to left-wing extremism.
One source expected European governments to receive many of the invitations. In November, the Trump administration designated four left-wing entities in Germany, Italy and Greece as foreign terrorist organizations under U.S. law. Seven people allegedly linked to one of those groups, known as Antifa Ost, went on trial in Germany in November on charges including attempted murder.
The source said administration officials hoped to announce a global coalition addressing antifa around the time of the planned conference.
Antifa, short for "anti-fascist," is not a centralized political group but is a decentralized movement without a clear structure, command hierarchy or leader, according to a 2020 Congressional Research Service report.
Some experts on political extremism, along with former FBI director Christopher Wray, have said that antifa may be more accurately understood as an ideology rather than a cohesive entity, and legal and civil rights advocates have expressed concerns that efforts targeting antifa could affect certain political expressions.
Supporters of the administration's focus on antifa point out that individuals who identify as antifa sympathizers have carried out acts of violence.
A federal jury in Fort Worth this month convicted nine people, who prosecutors said were antifa operatives, on terrorism-related and weapons charges for an attack on an Immigration and Customs Enforcement detention center in Texas last year.
Trump first sought to designate the movement as a domestic terror organization in 2020, when left-wing demonstrators attacked federal buildings in Portland, Oregon during weeks of unrest following the police killing of George Floyd.
A self-identified antifa supporter shot and killed a member of far-right group Patriot Prayer in Portland in August 2020, and was later killed by federal and local law enforcement officers.
Most Western counterterrorism officials are now focused on the threat of Iran-sponsored attacks directed at U.S., European and Israeli targets.
Ahead of the joint U.S.-Israeli attack on Iran on February 28, the FBI warned law enforcement agencies that Tehran might try to respond to any U.S. strikes by launching surprise drone attacks in California, according to a security bulletin seen by Reuters.
European police body Europol has warned that the conflict has "immediate repercussions" for European Union security, with an increased risk of acts of terror on the continent.
Both domestically and internationally, U.S. officials have in recent years placed greater emphasis on the threat of right-wing extremism compared to left-wing extremism.
However, Trump has made countering left-wing groups — and antifa in particular — a priority. He highlighted the movement during the 2024 campaign and said he would take action against left-wing groups he accuses of encouraging violence following the murder of conservative activist and ally Charlie Kirk in September.
Publicly available evidence in that case has not linked alleged attacker Tyler Robinson to antifa.
Shortly after the incident, Trump signed an executive order labeling antifa a "domestic terrorist organization."
Some legal experts have said the domestic terrorist designation may face constitutional challenges and raises free speech concerns.
