Later, I went down to the Washington field office and an onsite polygraph was administered.

I don't know Dr. Rosenberg. I have never met her, I have never spoken or corresponded with this woman. And to my knowledge, she is ignorant of my work and background except in the very broadest of terms.

And indeed, last week, the FBI executed a search warrant on my residence. This happened one day after my attorneys had left a message on the lead FBI investigator's voice mail confirming my continued readiness to answer questions and otherwise cooperate.

I acknowledge the right of the authorities and the press to satisfy themselves as to whether I am the anthrax mailer. This does not, however, give them the right to smear me and gratuitously make a wasteland of my life in the process. I will not be railroaded.

It's true that my research expertise is in biology: for example, the Ebola virus, the Marburg virus, and monkey pox, and not bacteriology as in the case of the anthrax organism. It's also true that I have never, ever worked with anthrax in my life. It's a separate field from the research I was performing at Fort Detrick.
