I don't recall that. Certainly Bush's guest worker program appears to be meant for Mexicans. The Dems have been smart enough to put a Rep label on comprehensive immigration reform despite the fact that the overwhelming Rep members of Congress [House and Senate] are against it. It is really a Dem/WH initiative.
I'll try to find an article describing what I think was the first attempt at amnesty by Bush.
I did find an article prior to 9/11 that is interesting. This article was dated 08/2001. Bush has been pushing this for years even after Mexico slapped him in the face regarding 9/11.
