The correct answer to this open question is the following.
The website article I choose is "The Press' role as a watchdog on government," written by Kent Auletta, published on the PBS website.
In this article, Auletta responds to a question regarding this function 0f the roles the press plays in a democratic society.
He says that the press as a government watchdog is necessary to keep people informed about what government officials and representatives are doing so the citizens can keep an eye on them.
This topic is of the utmost importance in that many times citizens forget to follow their officials and representatives' decisions and actions, believing that they are doing the right thing.
However, sometimes, politicians tend to serve the interests of political action groups that have their own interests at hand. That is why they hire lobbyists to negotiate with Congressmen. And these representatives were elected to serve the US citizens, not the political action groups.
