We do not need a NEW law, we just need to ENFORCE the current laws.
INDEED!
We as a nation need to insist that the President adhere to the obligations he is mandated to carry out in our Constitution i.e. "...he shall take care that the laws are faithfully executed..."
Article II Section 3
Actually, we could use a couple new laws. One that redefines a citizen by birthright as one born to a citizen or legal immigrant; one the explicitly states that no 'undocumented person' (or their children) are entitled to any federal $$$ - no food stamps, no medicare, no housing subsidies etc. If we do that, and enforce it, we could certainly slow down the problem without building the wall - or at least only those states that are in favor of it will be paying the bills rather than all of us...
