Oklahoma Man Arrested for Mailing Hundreds of Threatening Envelopes to Public Officials
Federal authorities arrested a 67-year-old Oklahoma City resident on Monday, charging him with orchestrating a campaign that targeted state election boards, members of Congress, election pollsters, media organizations, and others with hundreds of threatening letters containing suspicious white powder. Robin Patrick Martin faces federal charges including conveying false or misleading information and hoaxes, alongside mailing threatening communications, following an investigation that spanned both the 2024 and 2026 election cycles.
According to charging documents unsealed on Tuesday, Martin allegedly sent more than 700 envelopes across the country to public officials of both parties. The U.S. Department of Justice announced the charges, noting that the white powder included in the mailings was later determined by federal investigators to be non-hazardous. Even so, the calculated nature of the deliveries left recipients scrambling to verify their safety, turning routine mail openings into hazardous-materials incidents.
As alleged, Martin mailed letters containing white powder to hundreds of state and federal officials, a calculated attempt to terrorize public servants,
said Assistant Attorney General for National Security John A. Eisenberg, as reported by the Department of Justice. These officials were left to open those letters not knowing if the powder inside could sicken or even kill them, and that was the evident intent.

Tracking a Nationwide Mail Campaign
The investigation into Martin’s activities accelerated after October 13, 2026, when the Oklahoma State Election Board notified the FBI about a threatening letter containing white powder. That discovery connected to a broader, ongoing federal probe led by the FBI and the U.S. Postal Inspection Service, which had been tracking similar powdery mailings since 2024. Law enforcement officials determined that the envelopes had been sent to well over 100 locations, including multiple state secretary offices, election offices, and other recipients.
According to an FBI affidavit filed in the case, Martin allegedly used UV-reactive ink on the envelopes. Martin allegedly expressed grievances regarding the 2020 election, claiming that President Donald Trump won the 2020 election and voicing concerns regarding some of the same issues recurring in the then-upcoming 2024 election. Some envelopes bore return addresses linked to previous headquarters of the Green Party of the United States and the Democratic Socialists of America, though the DSA cooperated with the federal investigation.
Postal inspectors and partners identified related mailings and recovered the majority of these mailings before they reached their intended recipients. Postal inspectors utilized specialized mail flow expertise to identify related correspondence and successfully recovered the majority of the mailings before they reached their intended recipients. U.S. Attorney Robert J. Troester for the Western District of Oklahoma stressed that threatening election officials and attempting to intimidate public servants is a serious federal offense.
Martin Appears in Court and Faces Detention
Following his arrest on Monday, Martin made his initial appearance before U.S. Magistrate Judge Shon Erwin in Oklahoma City. Court records show that Martin was ordered detained pending a preliminary hearing scheduled for November 9, 2026.
The prosecution is being handled by the U.S. Attorney’s Office for the Western District of Oklahoma alongside the National Security Division’s Counterterrorism Section. The case falls under the umbrella of National Security Presidential Memorandum 7, an interagency federal directive aimed at protecting constitutional rights while targeting individuals and organizations engaged in political violence. Law enforcement agencies involved in the investigation included the FBI, the U.S. Postal Inspection Service, the U.S. Capitol Police, the Oklahoma City Police Department, and the Texas Department of Public Safety.
FBI Director Kash Patel credited the coordinated law enforcement response for apprehending the suspect. While the federal complaint lays out a detailed series of allegations—including surveillance footage showing Martin dropping off envelopes at a USPS facility and purchasing ingredients for the ink—court rules dictate that all defendants remain legally presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
