“No one who examined or viewed the anthrax spores mailed to the two senators in 2001 saw any coating on the spores.”
Apart from the people that saw a coating that is.

Last week officials went public with a more detailed profile of the bacterium being studied at the Army Medical Research Institute of Infectious Diseases at Fort Detrick, Md. It is highly concentrated and pure. The material’s light, fine texture and a brown ring around each spore suggest an additive had been introduced to prevent clumping.

The New York Times revealed in hushed tone that one unnamed expert said the floaty anthrax spores were surrounded by a brown ring, observable by microscope.

Investigators and experts have said the spores in the Daschle and Leahy letters were uniformly between 1 and 3 microns in size, and were coated with fine particles of frothy silica glass.

Government sources tell NEWSWEEK that the secret new analysis shows anthrax found in a letter addressed to Senate Judiciary Committee chairman Patrick Leahy was ground to a microscopic fineness not achieved by U.S. biological-weapons experts. The Leahy anthrax — mailed in an envelope that was recovered unopened from a Washington post office last November — also was coated with a chemical compound unknown to experts who have worked in the field for years; the coating matches no known anthrax samples ever recovered from biological-weapons producers anywhere in the world, including Iraq and the former Soviet Union. The combination of the intense milling of the bacteria and the unusual coating produced an anthrax powder so fine and fluffy that individually coated anthrax spores were found in the Leahy envelope, something that U.S. bioweapons experts had never seen.

Extensive lab tests of the anthrax powder have revealed new details about how the powder was made, including the identity of a chemical used to coat the trillions of microscopic spores to keep them from clumping together.

Scientists have found a new chemical in the coating on the anthrax spores mailed to journalists and politicians last fall, a high-ranking government official said Wednesday.
I repeat: NO ONE SAW ANY COATING.
You cite articles about a "brown ring." A brown ring is NOT a coating. There was never a good explanation of what the "brown ring" meant.
There were a LOT of newspaper articles about things that people BELIEVED were there or should be there, but NONE of these articles name any person who actually SAW a coating on the spores.
Shortly after the attacks, the media was filled with nonsensical articles about coatings. IT WAS ALL SPECULATION based upon mistakes made by people who had never seen dry spores before and didn't know what to expect. I go into great detail about this in Chapter 15 of my book, which you can read by clicking HERE.
All the experts who have actually seen the Daschle anthrax or images of the Daschle anthrax and who have been asked about coatings on the spores have stated that THEY SAW NO COATINGS ON THE SPORES.
