What a stupid statement..."too expensive"...
If Congress wants to get rid of the illegals they need only pass a law making it a federal offense to employ anyone who is not legally in this country. And, pass a second law, making it illegal for any federal/state/local governmental agency and/or not-for-profit to provide support to anyone who is illegally in this country.
If our leadership had the "stones" we could have the illegals running for the border, on their own dime, in just a few days.
Add to that the idea that we eventually use this as a plan to roll back the hog trough open to American citizens and I will vote for it right now! I would even vote for it WITHOUT that addition! Government "compassion" is legalized theft.
Of course, I find your first proposal abhorrent, but wanted to agree where I could.
