BOCA RATON, Fla. - Authorities are responding to a congressman's office in Florida after a letter containing some type of white powder was discovered.

Boca Raton Fire Rescue says a hazardous materials team was at Republican Allen West's office Friday to check whether the letter has any dangerous substance. Police are also responding.

West is freshman congressman and tea party favorite who swept incumbent Rep. Ron Klein from office. He's known for his straight-talking, fiery rhetoric and is no stranger to controversial statements.

A spokesman for West did not immediately return a call.
