FBI Accuses Oklahoma Man of Mailing 700 Threatening Letters

Federal authorities in Oklahoma City have charged a man with sending hundreds of threatening letters to public officials. The suspect, Robin Martin, allegedly mailed envelopes containing white powder and messages warning recipients of arrest for treason.

The investigation began in 2024 after election officials in multiple states reported receiving suspicious mail. The campaign continued through the fall of this year. According to court documents released Tuesday, the powders found in the packages were benign substances such as flour or yeast. However, the FBI noted that not every letter underwent a full analysis.

Martin was arrested on Monday. He was scheduled to appear before a federal court in Oklahoma City on Tuesday. He faces charges for spreading a false pretense and sending threatening communications through the postal service. One message, written in invisible ink readable only under ultraviolet light, instructed recipients to stay on the right side of history or their lives might depend on it.

The sender used the return address USTEA, or the United States Traitor Elimination Army, located in Takoma Park, Maryland. FBI Agent David Cole stated in an affidavit that investigators identified more than 700 related postal shipments made during the fall of this year. These packages targeted election officials, members of Congress, poll workers, media outlets, and federal agents.

The letters questioned the results of the 2020 presidential election and claimed Donald Trump had won. They expressed concern that similar issues would repeat in the 2024 election. A recurring threat warned recipients they could face arrest for treason or something worse. Federal authorities announced in October that they were investigating these suspicious mailings, which led to evacuations in election offices in Louisiana and Oklahoma.

Investigators identified Martin through video footage showing his vehicle stopping near postal offices in Oklahoma City, Dallas, and San Antonio in October. His fingerprints were recovered from a letter addressed to FBI Director Kash Patel. Walmart purchase records showed he bought curcumin and vinegar, which he allegedly used to create the invisible ink. The investigation also involved the Socialist Democrats of America, where Martin posted a message under the name George Livingston warning members about voting.

This case joins a separate federal investigation into threatening mail sent to members of Congress. Last month, a 37-year-old man from Illinois was accused of sending letters with white powder to lawmakers. One of those notes read, JA, enjoy the gift.
