The reason Bush and Cheney did not shout it out was that Republicans made them and sold them to bad guys.
Yeah, I remember hearing about that. Evidently most Republican offices on Capitol Hill had hidden chemical weapon factories in closets, and the Republican senators and representatives spent long hours personally manufacturing these weapons and having staffers sell them on street corners to anyone wearing a name tag which said "Bad Guy". The only way anyone found out was when visitors touring the Hill were affected by a leak of "Grey Poop-on-you" Mustard Gas emanating from the office of the ranking Republican.
I can't believe this news story was so quickly hushed by the current Democrat-led administration, considering their incredible record for transparency with the press. It's unlike them to hide things the way Bush and company did.
