Going after employers only would solve nothing. The illegal would just find another source of income. Removing the illegals stops the problem at the source. We need to go after employers too but one would assume this is everify and that needs to be passed by congress.
Going after employers and skinning them alive if they hire illegals would solve a lot.
Don’t nees any new laws to go after those that hire illegals.
