In the news industry everyone knows that the bad news always comes out on a Friday afternoon. Why? Because everyone also knows that most media has filed early and gone home for the day.
Seems the Bush administration pulled this little PR trick just last week with the release of its 19-month overdue US Climate Action Report. 
The report was released last Friday (July 27th) by the Department of State in the form of this media memo.  The release was not mentioned in the department's daily press briefing , nor is it mentioned in the news section  of the White House's Council on Environmental Quality website.
And did the Bush Administration succeed in avoiding any press? Almost. The Student Operated Press  reported it. No offense to the SOP, but I would say mission accomplished.
H/t to Rick Piltz and his great work on Climate Science Watch.
