TWIN PEAKS, California, Dec 1 (LSN) – Jeff White, director of Operation Rescue California and father of nine children received a letter at his home Monday which claimed he had been exposed to the deadly anthrax bacteria used in biological warfare. The FBI was called in to investigate and has retained the letter for its investigation. Authorities suspected that the letter, forwarded to White’s home from his pro-life office, was a hoax and no evacuation of the neighbourhood was deemed necessary. “It comes with the territory,” White said. White suspects radical abortion advocates are behind the threat. Since 1988, when he joined Operation Rescue, White said he has received dozens of death threats and is often informed of such threats by law enforcement agencies.
