From Edward J. Epstein:
"The National Commission on Terrorist Attacks Upon the United States reports that a Californian-trained biologist named Sufaat in 2001 spent 'several months attempting to cultivate anthrax for al Qaeda in a laboratory he helped set up' in Afghanistan and that this same biologist provided housing for at least two of the 9-11 hijackers in his Kuala Lumpur condominium."
