I have had nothing to do in any way, shape or form with the mailing of these anthrax letters, and it is extremely wrong for anyone to contend or suggest that I have.

After reviewing the polygraph charts in private, the polygraph examiner told me that I had passed and that he believed I had nothing to do with the anthrax letters.

As a scientist in the field of biological warfare defense, I have never had any reservations whatsoever about helping the anthrax investigation in any way that I could.

Anthrax is a deadly inhalational disease.

After eight months of one of the most intensive public and private investigations in American history, no one - no one - has come up with a shred of evidence that I had anything to do with the anthrax letters. I have never worked with anthrax. I know nothing about this matter.

I want to look my fellow Americans directly in the eye and declare to them, 'I am not the anthrax killer.' I know nothing about the anthrax attacks. I had absolutely nothing to do with this terrible crime.
