Oklahoma man charged over letters containing white powder sent to officials

Federal authorities charged an Oklahoma man with sending hundreds of letters containing nonhazardous white powder to public officials ahead of the 2024 and 2026 elections, the New York Post reported. [1]

According to the New York Post, Robin Martin faces charges of conveying a hoax and mailing threatening communications. The FBI stated in a court filing made public on Tuesday that the powders turned out to be yeast or flour, although not all of the letters have been fully tested. [1]

The New York Post reported that Martin was scheduled to make his initial court appearance on Tuesday afternoon in Oklahoma City. Online records did not immediately list an attorney representing him. [1]

This arrest follows similar recent incidents involving suspicious mailings. As FTMQ News reported earlier, election officials in Ohio, Louisiana, and Oklahoma received suspicious packages containing white powder in October 2026. Additionally, federal authorities arrested an Illinois man in late October 2026 for allegedly mailing letters containing unknown white powder to members of Congress. [2][3]
