Why was the Senate intel report a Friday release?

I have been wondering why the Dems in charge of the Senate Intelligence Committee released the pre-Iraq intel report on Memorial Day Friday.

You would think they would want to play up the fact that the Bush administration ignored loads of intelligence that predicted, with some precision, the current Iraqi chaos, but instead, it's buried on a holiday Friday.

Was that part of the Iraq funding "deal?" Bush doesn't crow if they bury this report?
