Former Sen. Alan Simpson of Wyoming, the co-author of the 1986 Simpson-Mazzoli immigration reform bill, has said the failure of that bill was a function of the lack of an ID card system.

I absolutely advocate for comprehensive immigration reform.

While the Pence-Hutchinson immigration reform idea is not perfect, it does represent a useful discussion point for future action. As diplomatically and kindly as possible, with all the greatest respect for differing points of view, let me just say that the Tancredo-Buchanan attack on Mike Pence is nuttier than a fruitcake.

It's a significant contribution if we can get immigration reform done.

I'm for immigration reform. I think the system's horribly broken, and we need to do something about it.

We must pursue immigration reform - it's something we have to do, something that starts with border security.
