Capitol Evacuation

Sen. Jeff Sessions, R-Ala., leaves an underground garage of the U.S. Capitol complex after he and other Senate staff were quarantined during a security scare in the Russell Senate Office Building on Capitol Hill, Feb. 8, 2006. Eight senators were among 200 people who were held in a Capitol parking garage for three hours after a security sensor indicated the presence of a nerve agent in their office building.
