Ah, that prior comment is dead.

So this is a source just saying they oppose inappropriate expansion. That they want PAs and NPs to practice as part of a team that includes a physician. I don't really see this as an issue. I also see PAs, NPs, and nurses as falling into the medical profession and subject to licensing, etc. So I see them as being on the inside of the system, not one of the "other people".

What I was specifically looking for was a source about the second part of this thread - the restriction of residency by the AMA.
