from the Miami Herald article you linked to:

The final report was completed in December. Since then a working group of Bush administration intelligence officials has ''scrubbed'' the report, objecting to additional public disclosures.

The two chairmen from Florida who oversaw the investigation, Sen. Bob Graham and Rep. Porter Goss of Sanibel, have pushed for months for more disclosure.

Graham, a Democrat running for president, has said the administration was using the excuse of national security to block ''embarrassments'' by the government.

Goss blamed the declassification battle on traditional resistance from intelligence officials.

Seven months - that's a significant delay. The fact that the delay is almost over does not negate its duration, nor its cause.
