A series of evacuations occurred across multiple states, including Iowa, Wyoming, and Kansas, after state election offices received suspicious envelopes containing unidentified white powder. The Iowa Secretary of State's office building was evacuated, while similar incidents prompted evacuations in Oklahoma and Wyoming, where authorities confirmed the substances were non-hazardous. Wyoming's Secretary of State Chuck Gray noted that the incident required law enforcement evaluation and investigations. In Kansas, the office was evacuated as a precaution after being alerted to a similar package received by Nebraska's election office. This wave of suspicious mail follows a previous incident last November involving envelopes containing dangerous substances sent to election offices in various states. Authorities are urging vigilance and caution in light of these events.
