i'm a little suspicious of stuff on the internet sometimes, and so i can't guarantee that everything about this video is true. the additional audio could have been dubbed in, and of course the words on the screen have been added by the original poster
have a watch & listen:
if that video is accurate, and you're a politician making that speech you know to stop right there, go off your script, and condemn such language.
especially in light of stories like this one.
