Appears as if the previous US administrations have ignored the Immigration laws to enhance cheap labor and influence voting through procreation of children on US soil.
Now it appears there is an Administration that intends to enforce the Immigration laws.
With all the riots and protesting, the efforts may be more productive in re-writing the Immigration laws. I've read the US Constitution and congressional laws were intended, at the will of the people, to change with future needs through the Amendment's.
