Rush did bring the issue of the birth certificate out on his show.
It is an important constitutional issue and one that is simple to rectify. Show the original certificate and close the case.
Rush said” it is a waste of time to talk about it because ,we can’t prove it.” And later he said” I don’t care where Obama was born, I don’t care what his birth certificate says.” I guess he doesn’t care what the truth is. So much for the detector of truth.
