In open court and legal filings it’s referred to simply as “the Document.”
Federal officials claim its contents are so sensitive to national security that it is stored in a bombproof safe in Washington and viewed only by prosecutors with top secret security clearances and a few select federal judges.

The Document, described by those who have seen it as a National Security Administration log of calls intercepted between an Islamic charity and its American lawyers, is at the heart of what legal experts say may be the strongest case against the Bush administration’s warrantless eavesdropping program. The federal appeals court in San Francisco plans to hear arguments in the case Aug. 15.

The charity’s lawyer scoffs at the often surreal lengths the government has taken to keep the Document under wraps.

“Believe me,” Oakland attorney Jon Eisenberg said, “if this appeared on the front pages of newspapers, national security would not be jeopardized.”

Eisenberg represents the now-defunct U.S. arm of the Al-Haramain Islamic Foundation, a prominent Saudi charity that was shut down by authorities in that kingdom after the U.S. Treasury Department declared it a terrorist organization that was allegedly funding al-Qaeda.
