COMO,
tsk, tsk.
totally disagree. 
Trump is doing all this backwards and cost us LOADS of money. 
Instead, if he phases in e-verify, once in, then anybody that remains outside of the system is here illegally. IOW, it becomes very trivial to locate these and send them home. 
More importantly, gangs will be trying to hide amongst the illegals that are left. 
It becomes cheap and easy to find them and send home the illegals and imprison the gang members (no sense sending that trash home; they will simply come back or attack that nation). 

Trump is a joke.
