This is why we need CONgress to solve this issue. 
They need to: 
1) phase-in e-verify over 2 years, 
2) decide in the first 6 months who will be allowed to remain and under what conditions.
3) and then at the end of that, go after what remains.
4) that means shutting down ALL sanctuary govs, along with harsh penalties for businesses that employ illegals, and finally, anybody caught harboring illegals esp gang related get 10 years in prison and if not citizens are sent back AFTER prison time.
