Anthrax Found at White House Mail Facility. WASHINGTON – Anthrax has hit an offsite White House mail facility and caused the death of two Washington, D.C., postal workers, authorities announced Tuesday. We're making sure the West Wing and the White House is safe, President George W. Bush said in a press conference. White House spokesman Ari Fleischer told reporters that anthrax had been found Tuesday at a mail-screening facility for the White House on a military installation. That facility was closed for testing and decontamination. All environmental tests at the White House itself have come back negative, he said.
