"We are still undergoing final tests to determine absolutely if these two deaths were related to anthrax exposure. The cause of death to date is unclear, but I'll tell you what is very clear. It is very clear that their symptoms are suspicious and their deaths are likely due to anthrax."

The anthrax situation in Washington D-C has become more serious.
Health officials on Monday said two postal workers in the Washington area had been diagnosed with inhalation anthrax and two more employees at the same place had died of symptoms consistent with this rare form of the disease.
Speaking at a news conference, the city's chief health official said the unidentified man diagnosed with the disease was hospitalised in suburban Virginia, at the same facility where another postal worker was diagnosed over the weekend.
Authorities were also conducting tests on clinical samples from the two postal workers who died after showing symptoms consistent with anthrax.
Doctor Ivan Walks said authorities are investigating nine more cases that have aroused concern.
He said he did not know how many of the nine were postal workers or how many were hospitalised.
The disclosures came as postal workers lined up by the dozens for testing, and city authorities urged anyone connected with the affected Brentwood central mail facility to come forward immediately for screening.
A spokesperson for the U-S Postal Service said there are roughly 2-thousand employees at that Brentwood postal facility in Washington.
Over the last two and a half weeks four men, including one who died, have been diagnosed with inhalation anthrax, a disease not seen in this country since 1978.
Six others, including two postal workers in New Jersey, have been infected with a highly treatable form of anthrax that is contracted through the skin.
Thousands have been tested for exposure to the bacteria.
City officials made their startling disclosures as the Capitol reopened but congressional offices remained shuttered for environmental testing.
Congressional sources said it was unlikely that all the House and Senate office buildings would reopen on Tuesday, as officials had hoped.
Speaking at a photo opportunity with Israeli Foreign Minister Shimon Peres, Senate Majority Leader Tom Daschle said it will be the "next few days" before they're ready to reopen.
Environmental sweeps have been done in the buildings since last week's discovery of an anthrax-laced letter in Daschle's office.
Daschle expressed his condolences to the families of the two postal workers who died from symptoms consistent with anthrax, but he said it's important not to "draw any premature conclusions about what happened and how it happened."
Investigators also discovered anthrax over the weekend in a building where mail for House offices is processed.
These officials said there had been no test results yet indicating anthrax in any of the other House office buildings, leaving authorities to wonder whether an as-yet undiscovered piece of mail was the source of spores found on a mail room machine.
