I don’t understand. Can she prove the government is the one that furnished the anthrax, or that it came from a government lab? If the US gets nuked, I hardly think you can sue because the US didn’t control nuclear weapons well enough.

The problem the lawyer has is that there are 20,000+ Capitol Hill employees and 3,000+ USPS employees (who were exposed) who can then walk into court and simply ask the judge to provide them with the same "settlement".
So, for the sake of wrapping this up quickly, let's say all she wanted was $500,000. With 25,000 other claimants, more or less, that's over $12 billion.
It is highly unlikely that any US Attorney, even the Attorney General, has the authority to accept/pay a settlement on his own that is that large. This sucker would need to go to Congress.
