However, it's a good way to get an idea of the major problems facing Americans.
ProPublica is a nonprofit news agency founded and run by former New York Times and Wall Street Journal editors and journalists. Its purpose is to promote unbiased, investigative journalism in a time when many news agencies are only printing sensational stories, "the stuff that will sell." Very interesting site!
