"(President-elect Donald Trump) can build a wall 100 feet high and 50 feet deep, but it is not going to keep family members separated.

So if someone is deported and they have family members here ... they will find a way back — whether it is through the air, under a wall, through the coast of the United States," Trevino said.
This is pretty much a known fact. That is why we must take interior enforcement very seriously and deport every illegal that comes into contact with law enforcement. Furthermore, we need to resume business raids, roadblocks, and other enforcement activities that have fallen by the wayside since Obama took office! Before any individual illegal is deported, that person should be questioned extensively about other family members that are here illegally so they can be deported as a family unit. We need to be actively seeking out and deporting whole families of illegals, not just individual family members.
