Did anyone watch Lawrence O'Donnell on MSNBC?

He played some private audio tapes of Richard Nixon's racist and anti-Semetic rantings for some reason. The comments were made in private and most people talked that way and held those views then. In fact, most Presidents were racist and anti-Semetic whether Dem or Repub so I dont know why he was on a tear over Nixon. Over the last 30 years a lot has changed.
