Ex-Marine Nazi leader who once urged execution of judges arrested by FBI

A neo-Nazi who embraces terrorism has been ordered held in pre-trial detention as a danger to the community by a federal magistrate judge following his arrest for illegally possessing a firearm.

Mathew David Bair, a leader of the neo-Nazi accelerationist group Injekt Division, was arrested in Pennsylvania by the FBI last week.

A former Marine who was court-martialed out of the service for larceny and sale of classified materials, Bair joined the riot at the U.S. Capitol as a member of First Capitol Proud Boys, as Trump supporters attempted to overturn the 2020 election on Jan. 6.

From his time as a Proud Boy, Bair increasingly gravitated to a violent brand of white supremacist extremism. He toldRaw Story in 2024 that “the fascist pipeline is very real,” and that he had been “in a direct pipeline chapter.”

Bair’s radicalization led him to Injekt Division, a neo-Nazi accelerationist group whose former leader was arrested in May 2021 for allegedly plotting to carry out a mass shooting at a Texas Walmart.

“I would say they’re very much in line with the Terrorgram milieu,” Hannah Gais, a senior researcher and journalist at the Southern Poverty Law Center, told Raw Story. “I think obviously given their origin, they have clear ties to violence.”

Terrorgram Collective is a global network that has encouraged mass shootings, political assassinations and infrastructure attacks through online propaganda, which inspired a deadly school shooting spree in Brazil, a fatal mass shooting at an LGBTQ+ bar in Slovakia and a mass stabbing in Turkey, as well as assassination attempts and thwarted attacks on electrical substations. Dallas Humber, one of the group’s leaders, is currently serving a 30-year prison sentence after pleading guilty to soliciting hate crimes and murder.

In 2023, Bair posted a video depicting a flyer reading, “Shoot your local judge.” Asked about the flyer by Raw Story, Bair brought up an incident in which an extremist went to the home of U.S. District Court Judge Esther Salas and fatally shot her son. Salas has frequently spoken out against threats directed at judges who cross President Trump over the past year.

Extremist researchers and antifascist activists have closely monitored Bair due, in part, to his provocative online presence. They include a Telegram message showing members posing in tactical gear and skull masks outside what appears to be a power plant while displaying firearms and their group flag.

Another Telegram message linked to Bair shows a ballistic vest, flags and pistols draped over a car seat accompanied by text indicating the author was traveling to Washington, DC on Jan. 24, 2025, a date that coincides with the March for Life. The annual event typically draws both far-right extremists and left-wing counterprotesters. Carrying firearms is prohibited in Washington, D.C., with a few exceptions that include law enforcement.

An indictment returned on March 4 alleges that Bair possessed an Aero Precision rifle and Ruger pistol while knowing that he had been convicted of a crime punishable by imprisonment for more than a year. Bair pleaded not guilty following his arrest on March 11.

A magistrate judge in Harrisburg, Pa. ordered Bair to be held in pre-trial detention, partly on the basis that his release poses serious danger to a person or the community. The magistrate also cited Bair’s prior criminal history, prior parole violations, prior failures to appear in court, and the strength of evidence supporting the gun charge.

Dawn Clark, a public affairs officer with the U.S. Attorney’s Office for the Middle District of Pennsylvania, declined to comment in response to questions about why the government argued that Bair is a danger to a person or the community, or whether the government is concerned that Bair has attempted to intimidate judges.

Beatrice Diehl, an assistant federal public defender assigned to represent Bair, also declined to comment.

While becoming increasingly immersed in violent neo-Nazi activity, Bair remained committed to Trump. In July 2024, shortly after Trump accepted the nomination at the Republican National Convention, an Injekt Division Telegram channel linked to Bair posted video of a rally in Michigan in which neo-Nazis chanted, “We love Hitler, we love Trump.”

In late 2023, Bair joined 2119, a teenage neo-Nazi gang, after four of its members, ages 15 to 18, were arrested in Pensacola, Fla. for a hate-fueled vandalism spree that included brick attacks on two synagogues. 2-1-19 is an alphanumeric code that stands for Blood and Soil, with 2 representing B for “Blood,” 1 representing A for “And” and 19 representing “S.” for “Soil.” Blood and Soil is the English translation for Blut und Boden, a popular phrase during the Third Reich that suggests a mystical bond between a racialized ideal and the land of Germany.

The group previously went by the moniker Revolutionary White Brotherhood, or RWB.

Then 34, Bair was by far the oldest member of 2119, which was the focus of a February 2024 investigation by Raw Story. Bair posted a photo on the social media platform Telegram that showed his 4-year-old son posing next to 2119 graffiti.

In March 2024, the [2119] Sons of Pennsylvania Telegram channel, likely operated by Bair, posted a video of two men driving a pickup truck to the Pennsylvania State Police barracks in York, and depositing a brick inscribed with the letters R-W-B at the front door, declaring as they departed: “White f------ power.”

2119 went into decline following the Raw Story investigation. By mid-2014, the group had disbanded as its leader lowered his profile and members found themselves caught in the middle of intra-movement rivalries between larger white nationalist organizations. Injekt Division likely contributed to 2119’s demise by doxxing a leader of 2119’s California chapter after he admitted to “snitch[ing] on” another member.

Bair is not the only associate of 2119 who has faced arrest in recent months.

Aiden Cuevas, an Alabama neo-Nazi who enthusiastically promoted 2119, was indicted alongside Andrew Nary for conspiracy to traffic firearms after allegedly buying machine guns from an undercover FBI employee while planning to start a paramilitary and requesting training to “take out” so-called “high-value targets.

Cuevas and Nary both entered not guilty pleas before a federal magistrate judge in Huntsville, Ala. last week.

Last month, David William Fair, a probationary member of the racist skinhead group Vinlanders Social Club, was indicted in North Carolina for felony soliciting gang activity and contributing the delinquency of a minor.

Fair had administered a Telegram chat that Bair joined in 2023. That same year, following the Pensacola arrests, Fair counseled Cuevas in another Telegram chat that 2119 should exercise more discretion to avoid criminal prosecution.

The story previously stated that Bair and a second man deposited a brick outside the York Police Department. The story has been corrected to reflect that they deposited the brick outside a Pennsylvania State Police barracks in York.
