Federal investigators say an Oklahoma City man sent hundreds of threatening letters containing white powder to election offices, lawmakers and other public officials during the 2024 and 2026 election cycles, prompting security alerts and evacuations across multiple states.

OKLAHOMA CITY — Federal authorities arrested an Oklahoma City man Monday, Nov. 2, accused of mailing more than 700 threatening letters containing suspicious white powder to public officials, election administrators and other recipients across the United States, culminating in federal criminal charges announced on Election Day.

Robin Patrick Martin was charged with conveying false or misleading information and hoaxes and mailing threatening communications after an FBI investigation connected him to letters distributed during the 2024 and 2026 election cycles. The envelopes were sent to more than 100 locations, including congressional offices, state election agencies, polling organizations and media outlets, according to a Nov. 3 report by Fox News Digital.

Federal investigators determined that samples of the suspicious substances contained yeast or flour rather than hazardous biological materials, although testing had not been completed on every envelope. The mailings nevertheless triggered emergency responses, including evacuations at election offices in Oklahoma and Louisiana, as authorities worked to determine whether recipients faced a genuine chemical or biological threat.

According to charging documents described by CBS News, the letters included messages written in ultraviolet-reactive ink that were difficult to detect without specialized lighting. Investigators said the communications referenced a purported organization called the United States Traitor Elimination Army and threatened recipients with arrest for treason or more severe consequences.

Some letters contained lengthy political statements, while others warned officials that they would face punishment for alleged misconduct. The FBI said the 2026 communications specifically concerned the November midterm elections, raising concerns about intimidation directed at election workers and government officials responsible for administering the vote.

Investigators reportedly connected Martin to the mailings through surveillance recordings, postal records, fingerprints and evidence of purchases associated with the envelopes and ultraviolet-reactive writing materials. Video footage allegedly showed his vehicle stopping at postal facilities in Oklahoma City, Dallas and San Antonio during periods when suspicious letters were mailed.

Federal authorities also identified fingerprints on a letter addressed to FBI Director Kash Patel. Investigators further alleged that Martin used the name George Livingston in communications, including a threatening message sent to a Democratic Socialists of America email list.

The arrest followed weeks of heightened security concerns surrounding suspicious mail received by government offices. In October, the FBI and U.S. Postal Inspection Service warned that letters containing unidentified substances had been sent to congressional offices and state election agencies nationwide. The Senate sergeant at arms also alerted congressional staff that additional mailings could reach their destinations despite efforts to intercept them.

As The Associated Press reported Tuesday, authorities advised recipients to treat suspicious envelopes as potentially hazardous until the substances could be examined. Several election offices temporarily evacuated buildings or initiated emergency procedures while investigators assessed possible threats.

The investigation involved the FBI’s Oklahoma City field office, the bureau’s Criminal Division, the U.S. Postal Inspection Service, U.S. Capitol Police and the Oklahoma City Police Department. Federal investigators have not publicly established a definitive motive for the alleged mailings or identified evidence that the suspect acted on behalf of an actual organization.

The case has drawn particular attention because of its timing. Election officials nationwide were already preparing for increased security and public scrutiny during Tuesday’s midterm elections, when Americans are voting to determine control of Congress and numerous state governments. Threatening communications directed at election administrators can disrupt government operations even when the substances involved are ultimately determined to be harmless.

According to Reuters’ account of the federal charges, the alleged recipients included public officials from both major political parties, election administrators, pollsters and news organizations. The investigation therefore encompasses a broader range of targets than any single political party or jurisdiction.

Martin was scheduled to make his initial appearance in federal court in Oklahoma City on Tuesday afternoon. Court records available when the charges were announced did not identify an attorney representing him, and no plea had been reported.

The charges remain allegations, and Martin is presumed innocent unless proven guilty. Federal authorities continue examining the mailings and associated evidence as they seek to determine the full extent of the alleged campaign and whether additional criminal conduct occurred.
