Health officials say fewer people than originally thought were exposed to anthrax at the U.S. Capitol. Thirty-one people originally tested positive, but futher tests show three of them were not exposed to the bacteria. Results also came back negative today for another 13-hundred congressional staff members tested for anthrax exposure. The staffers were tested after a letter containing anthrax was mailed to Majority Leader Tom Daschle. Allison Dobson, an aide to Minnesota Democrat Paul Wellstone, is among those tested. She says staffers are very relieved.
