Washington — An Oklahoma man faces federal charges after allegedly sending hundreds of letters containing white powder to public officials and media outlets ahead of both the 2024 and 2026 elections.
According to charging documents unsealed on Tuesday, Robin Patrick Martin allegedly sent more than 700 envelopes to public officials of both parties across the country.
