Here's an interview with Ambassador Joseph Wilson -- the guy that's been touring the circuit explaining how he discovered the Niger Uranium WMD situation couldn't have happened as originally reported.
This is from the July 24, 2003 show.
This is a long interview, so I've made it available in its entirety and in two parts.
