From the CNN story:
Asked whether the Bush administration planned to announce the end of the physical WMD search, [White House Press Secretary Scott] McClellan deferred to Duelfer.
"I think it's up to him to make those determinations," McClellan said.
Lovely. I've heard a rumor that the search was officially over before the election, but I can't verify it.

This is a handy comparison of the WMD issue versus the CBS issue-- sort of a cost-benefit analysis. Just a friendly reminder of what the media is choosing to cover.
