Why must CNN follow our President-elect?

I'm serious, I was watching CNN news this morning, as dad had put it on, and they were talking all about how President-elect Barack Obama was taking his children to school, which any father would do, but they even had video. Why are they just intruding on his life? What are they going to do next, have a video of what he does everyday, what he has for breakfast? Isn't this intruding on his privacy? Why can't they leave him alone? I know he's going to be the first black president, and that is history in the making, but why do they have to intrude on his privacy? I know that it's only natural, and they most likely do this with celebrities, but why intrude on his privacy so much, because shouldn't the president-elect have more privacy, even though he is such an important person?
