Eight people were taken to area hospitals after a suspicious substance was found Friday morning in an office at the Longworth House Office Building, according to a D.C. fire department spokesman. The spokesman, Timothy Wilson, could not immediately describe the symptoms but said they were minor. He said fire crews evaluated 10 people and took eight to hospitals.
Captain Kimberly Schneider, a spokeswoman for the U.S. Capitol Police, had no immediate information on what the substance might be. Police said the substance was found in Suite B-227, the First Call Service Center. No offices at the building on Independence Avenue were evacuated. It is located just south of the U.S. Capitol and near the Capitol South Metro station. FULL REPORT
