I strongly recommend this episode of Bill Moyers Journal dealing with the subject of impeachment. The guests are Constitutional law expert (and conservative) Bruce Fein, and political journalist (and liberal) John Nichols. If you unable to download the episode from this page, you can read the transcript here.
It’s good to hear this subject being discussed intelligently on the airwaves. I was beginning to wonder whether anyone in this country even remembered that we have a Constitution. Most of our politicians certainly seem to be a gang of Constitutional amnesiacs. At any rate, read or watch it. I thought I wouldn’t need to (I know very well where I stand), but once the episode began, I was too absorbed in it to change the channel. This is worth watching.
