I'm not sure if this is the right place for this question, which would probably fit best in a AskPoliticalScience setting. Sorry if it's out of place.

After seeing this thread today in /r/CampingandHiking, I found this press release about the bill in question on the majority site for the Natural Resources Committee. That release is so obviously biased that it hurts, but then i found the minority site for the same committee, which has just as much shlock from the other side of the aisle.

So how do these sites (and the committees they represent) work? Who pays for the hosting and the staff that runs them? How are their budgets decided? If it's public money, shouldn't there be a single site for each committee that only presents an objective coverage of the bills, without all the sales talk? It seems to me that these sites are nothing more than campaign sites for the Representatives backing those bills. Shouldn't that, then, be paid for by the representatives themselves, their political parties, or the lobbyists who wrote the bills?

Or am I fundamentally misunderstanding how the committee system works?
