"A letter written in 1995 by former CDC Director David Satcher to
    former Senator Donald W. Riegle, Jr., points out that the U.S. Government
    provided nearly two dozen viral and bacterial samples to Iraqi scientists
    in 1985--samples that included the plague, botulism, and anthrax, among other
    deadly diseases. According to the letter from Dr. Satcher to former Senator
    Donald Riegle, many of the materials were hand carried by an Iraqi scientist
    to Iraq after he had spent 3 months training in the CDC laboratory. "
