Hatfill said he remains willing to cooperate with investigators, and that he consented to the June search in an effort to clear his name. Glasberg added Hatfill would have consented to the August search even if agents had not displayed a warrant.
"As a scientist in the field of biological warfare defense, I have never had any hesitation whatsoever in helping the anthrax investigation," Hatfill said.
Hatfill's property has been searched twice in the probe — with his consent in June, and with a warrant on Aug. 1.
Following the first search, agents said they found nothing immediately incriminating in Hatfill's apartment and storage shed.
Hatfill said he understood his background and controversial comments made him a logical subject for investigation, but he objected to government leaks and media zeal that have made him, "the currently designated fall guy."
"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 Sunday he has received standard government vaccinations or boosters for anthrax but that the last one expired by September 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 in the news conference 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.
Sunday, the FBI responded to Hatfill's and Glasberg's remarks, saying, "credible allegations concerning mishandling of evidence will be investigated thoroughly."
