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.

Anthrax is a deadly inhalational disease.

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.

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.

I am extremely proud of my service with the government and my efforts to help safeguard public health and protect our country against the scourge of offensive biological warfare.

All Americans value the freedom of speech and the freedom of the press, and I believe this is essential for our continued way of life. But with this freedom comes responsibility. That responsibility has been abdicated here by some in the media and some in the government.
