Via FRONTLINE: “On Oct. 15, 2001, Senate intern Grant Leslie opened a letter addressed to then-Senate Majority Leader Tom Daschle (D-S.D.). White powder poured onto her lap, her shoes and the floor. Eventually, the entire building would have to be shut down. Leslie and her colleagues were given Cipro and vaccinated. It would be the most high-profile of the series of biological attacks that terrorized the country.”
Leslie spoke about the experience for the first time to FRONTLINE.
