The Hoeven-Corker border security amendment to the Gang of Eight comprehensive immigration reform bill is finally out, and it is huge. Released in several parts, it totals 1,190 pages, amounting to a rewrite of large portions of the original bill. While much of the text of those 1,190 pages duplicates portions of the original legislation, there are entirely new passages and significant changes throughout — enough to keep anyone who cares about what is in the bill busy for quite a while.

The problem is, they don’t have quite a while. The Senate will likely vote on the amendment on Monday. That’s not much time to read and digest such a momentous and far-reaching piece of legislation.
