Authorities in Boca Raton, Fla., responded to Rep. Allen West's office on Friday after a letter containing white powder was discovered, the Palm Beach Post reports.
A hazardous materials team tested the powder and determined it was not anthrax or any other biohazardous material, although an accompanying letter mentioned anthrax. By 4:30 p.m. emergency officials declared the threat over.
FBI officials also responded to the suspicious letter, which included derogatory references to West, an African-American.
In an statement, West said he was "deeply disturbed" by Friday's events. "I thoroughly condemn this act which does nothing but evidence the sick and deranged nature of the perpetrator. I will continue to serve the constituents of Florida's Congressional District 22 with honor and integrity."
Boca Raton is the city where anthrax was discovered in an envelope sent to American Media Inc. in 2001.
