16. Various shots of Senate staffers lined up outside the Library of Congress for anthrax testing
Despite the anthrax scare, U-S Senators refused to let it completely close
close down the Capitol.
In a show of solidarity, the majority and minority leaders announced that senators would be in the chamber and voting on Thursday.
Tests found that at least 31 people in the Hart Senate Office Building were exposed to anthrax on Monday when a powdery substance fell from a letter to Senate Majority Leader Tom Daschle.
Senator Bill Frist, who is also a doctor, believed tests performed on some 12-hundred people at the Capitol complex were likely to show at least a few more were exposed to anthrax.
The search for the bacteria's source led congressional leaders to close six House and Senate office buildings for investigation and decontamination on Wednesday.
It will be shut down until next week after the buildings have been thoroughly scoured for anthrax spores.
Those exposed included 23 members of Daschle's personal staff, five law officers and three aides to Wisconsin Senator Russ Feingold, whose office adjoins Daschle's in the Hart building.
Daschle said none of those who tested positive for exposure was ill, although they were taking medication.
In shutting down operations for the weekend to allow for extensive testing, House leaders originally thought the Senate would join them.
But senators decided to work on from the Capitol, searching out office space for senators too junior to have Capitol offices and meeting in rooms designed for much smaller crowds.
But even with the House closed and the Senate working with skeleton staffs, employees on Capitol Hill continued to line up Thursday morning for more testing and to receive an antibiotic if necessary.
A Centers for Disease Control spokesperson said a "couple of thousand" people in all had been tested at the Capitol since Monday.
Of the results in hand, she said there were 31 positive for exposure and 155 negative.
Three government officials said Wednesday there was no evidence of any foreign or terrorist involvement in the powder contained in the letter to Daschle, although they continued to investigate that possibility.
One official said there was evidence that could point toward a domestic culprit.
