A worker in CBS News anchor Dan Rather's office tested positive for the external form of anthrax, the same form that earlier infected an aide to NBC's Tom Brokaw. The CBS employee is being treated and is expected to recover, authorities said. The news came as six Capitol buildings in Washington were closed for testing after 31 Senate workers tested positive for exposure to - but not infection from - the bacteria. The House chamber is closed through Tuesday as a precaution, although the Senate remained in session under tight security. (Related stories, pages 1, 2; related opinion, page 11.)
The FBI, meanwhile, said it is offering a $1 million reward for information leading to the arrest and conviction of persons responsible for mailing anthrax to at least three states. Five people have been diagnosed with anthrax symptoms nationwide, and 40 others have tested positive for exposure to it.

The remains of three people have been removed so far from the wreckage of the Japanese fishing vessel Ehime Maru, which accidentally was rammed by a US submarine off Hawaii in February during a rapid-surfacing drill. Six more men and boys aboard the vessel at the time are still missing. The ship was raised from the 2,000-foot-deep waters where it sank and towed to shallower water a mile off Oahu. Ultimately, it will be towed back to sea to sink.
The number of Americans filing new claims for unemployment benefits climbed last week by a seasonally adjusted 6,000 - to 490,000, the Labor Department reported.

More than 200,000 layoffs, many in the travel and tourism industries, have been announced since the Sept. 11 terrorist attacks. (Related story, page 2.)
