Our Republic (which the USA is, we are NOT a democracy) suffers when the supposed purveyors of facts aren't reporting complete facts.
So what do you suggest? The 1st amendment says Congress shall make no law. So the government can't impose any rules on news. The news system we have is free market, so advertisers pay for it based on audience, not based on facts or truth. People apparently have their own views on what are facts, and those views drive what gets reported in the news.
