Then what’s the holdup?
Good question? The law is clear but they go threaten to cut off federal funds when clearly they have much more power in the existing law.
I can't quote any law for this one but I heard Rush say one time that any politician or agency that allowed an illegal to stay was liable for any crime or damage that illegal committed. That was enacted when they made some deal with Clinton to get something he wanted passed. You would think that the current congress as a whole, has no clue what laws they pass or why.
