Authorities say a white powder found in a letter sent to a Florida congressman is not anthrax.
Boca Raton Fire Rescue spokesman Frank Correggio says no dangerous substance was found at the office of Republican Allen West on Friday.
West's chief of staff says the letter contained derogatory comments about the politician and contained the word anthrax. He says the letter was opened by a campaign staffer.
West is a freshman congressman and tea party favorite who swept incumbent Rep. Ron Klein from office. West was in Washington when the letter was opened.
He says in a news release he is deeply disturbed by the incident.
