The Justice Department has finally released a trove of filings from the anthrax investigation. You can see them here. A press conference is scheduled for 3:30 p.m.

The most informative documents are affidavits by investigators in support of search warrants. Here (PDF), for instance, is an affidavit by a U.S. postal inspector in support of a search warrant of Bruce Ivins' house, cars and safety deposit box. It's dated Oct. 31, 2007. In the affidavit, the investigator lays out the reasons for suspecting Ivins. Here's a glimpse at what the Wall Street Journal found in the documents:

One of the most intriguing pieces of evidence is an email the affidavit says bears similarities to the language used in the poisoned letters. A few days before the attacks, he sent an email that said: "Bin Laden terrorists or sure lave anthrax and sarin gas" and have "just decreed death to ail Jews and all Americans," according to the document.

The letters read: "WE HAVE THIS ANTHRAX . . . DEATH TO AMERICA . . . DEATH TO ISRAEL."

We'll have a round-up tomorrow morning of coverage of the release.
