SALT LAKE CITY (AP) -- The FBI says a suspicious powdery substance found in a package last week addressed to Gov. Jon Huntsman has tested negative for any biological toxins.
A portion of Huntsman's office was evacuated Thursday when the substance was found. It field tested negative for any toxins at the time, and the FBI said Monday that local laboratory testing also showed the powder tested negative for any known biological agents or toxins.
The substance will now be sent to FBI headquarters in Quantico, Va., to determine what it is along with other suspicious powders sent to state capitols in more than 30 states.
The letters, all postmarked in Texas, began arriving at governors' offices across the country last week. So far field tests have indicated the powders to be harmless, though further testing is under way.
