if you go to the links it clearly shows in text and is available as an audio clip of him saying something followed up by where and what he made up or lied about.
i will grant that the point of the website media matters is to point out lies in conservative media outlets. what i do not get is what is wrong with that. if its accurate information then who cares if the source is left wing or right wing. find me a conservative outlet that is actively policing other conservative sources and I guess we can use that information. either way, it still stands that Rush makes things up on his program.
