Here is a yahoo story;

Well no it is an AP story. Well not really it is the author's story. Ah shoot no it is neither. It is a press release. No I think it is blatant government propaganda.
I cannot find him right now (perhaps findlaw) but there are some great legal beagle publications in this area. Trouble is, it will make your head spin.

It is also great to review US stuff on equal time campaign advertising, simply for knowledge not for propaganda.
Thank you for your contribution to expanding all of our awareness.
