A envelope containing a white powder and marked "Tea Party" was sent to U.S. Rep. Joe Garcia's Key West office Wednesday.
The building was evacuated.
“Whether this is a hoax or a legitimate threat, this is a serious matter and should be treated as such," Garcia said in a statement. "Such scare tactics targeted against any elected official, or public servant, will not deter us from serving our constituents, as we will not be intimidated by these cowardly acts."
Capitol Police and local authorities are investigating.
