Sweet Sixteen

Gadflyer has sixteen questions which Bush should be forced to answer at the debates. Here's the first one:

On December 21, 2002, in the Oval Office with then-CIA director George Tenet, you expressed shock to Mr. Tenet that the evidence regarding Iraqi weapons of mass destruction was so thin. Yet just five weeks later, in your State of the Union address, you showed little if any doubt whatsoever that Iraq was a certifiable threat. What new information came to your attention that changed your mind so dramatically in just a few weeks during January 2003?

The best questions are rhetorical, aren't they?
