This amounts to the government paying for propaganda. Sorry, but that's how I see it. Yes, PBS does it all the time, but if I'm not mistaken, this is illegal. If this goes to an investigation, it would be a great way to give the entire government subsidized broadcast industry a giant enema.
Maybe if Williams was against "No Child Left Behind" before the government contract and for it after, it could be considered a bribe or unethical, but how is supporting an ally of a policy "illegal"?
How about attempting to understand your subject before jumping in next time?
