"This does not … give them the license to smear me and gratuitously make a wasteland of my life in the process," he said. "I will not be railroaded. I am a loyal American."
‘Never, Ever Worked With Anthrax’
Hatfill has worked closely with the military and CIA anthrax experts and has frequently shocked his colleagues with his statements and demonstrations of how easily terrorists could make biological weapons, sources said.
Hatfill said today he has received standard government vaccinations or boosters for anthrax but that the last one expired by Sept. 2000, making him just as vulnerable to exposure as any unvaccinated member of the public. He added that although he has commented on bioterror, his work focused on viruses and did not involve anthrax.
"I have never, ever worked with anthrax in my life," he said. "It's a separate field from the research I was performing at Fort Detrick."
In 1999, however, while working for a government contractor, Hatfill commissioned a study detailing how a hypothetical anthrax attack could be carried out by mail.
Hatfill lost his government security clearance Aug. 23, 2001, for reasons that remain unclear. Glasberg declined to answer a reporter's question on the circumstances surrounding the loss of the security clearance.
Hatfill said he later was fired from the government contractor's job and placed on leave at a new job at Louisiana State University largely because of "defamatory speculation, innuendo and other accusations about me."
Biological Attack Novel
Glasberg revealed today that Hatfill has been working on a novel. Part of the manuscript has been obtained by ABCNEWS affiliate WJLA-TV in Washington.
"This novel written by Steven Hatfill envisions a biological attack on Congress," said Rebecca Cooper, a reporter for WJLA. "It's an attack so deadly that not only do members of Congress and congressional aides become ill, but hundreds of Washington residents become ill and many die as a result."
Glasberg said the novel was stored on a computer seized during one of the searches, and alleged investigators may have leaked it to the media. However, it was unclear how WJLA obtained the manuscript portion.
Late today, the FBI responded to Hatfill's and Glasberg's remarks, saying, "Credible allegations concerning mishandling of evidence will be investigated thoroughly."
Investigators are intrigued by the fact that Hatfill lived for years near a Greendale Elementary School while attending medical school in Zimbabwe, ABCNEWS has reported. Greendale School was the phony return address used in the anthrax letters.
However, Glasberg denied Hatfill knew of such a school in Harare, Zimbabwe.
"There is a subdivision in Harare called Greendale, [but Hatfill] did not live there," Glasberg said. "The information we have is that there is no such Greendale School."
Since the wave of attacks, the FBI has been unable to find out who was behind the anthrax-laced letters. There have been few leads and investigators have admitted that the trail seemed to have grown cold.
Fort Detrick, which also is home to the U.S. Army Medical Research Institute of Infectious Diseases, has anthrax samples, and the FBI is conducting voluntary lie detector tests at the base. Lie detector tests and interviews are also being conducted at Dugway Proving Ground in Utah, where researchers have been developing a powdered form of anthrax for testing biological defense systems.
Small quantities of anthrax have routinely been produced at Dugway, and then shipped to the Army's bio-defense center at Fort Detrick, Army officials have said.
