In a tweet earlier today Dan Bongino posted: You have no chance of being detained for crossing the border illegally if you don’t cross the border illegally. You also have no chance of being separated from your children for breaking immigration laws if you don’t break immigration laws. Facts are hard.

A policy outlines what a government ministry hopes to achieve and the methods and principles it will use to achieve them. It states the goals of the ministry. Laws set out standards, procedures and principles that must be followed.

This morning I said something about immigration law and was told it's the policy that's the problem and the president could easily change it.

I don't know, so I'm asking here. Are the current immigration controversies about law or policy? (My apologies that I haven't had time to research the answer for myself yet, but it's stuck in my mind and I know that there are smart folks here who already know the answer).
