Will he really build a wall?
Maybe, but that won't stop immigrants. As a comparison, the UK and France have a sea between but immigrants still get into the UK illegally.
The difference is, in Britain, immigrants enter lawfully if not legally. But this is not true in France. Lawfully and legally are the same in France.
In America, if any man or woman calls out any government man or woman in court, the government man or woman must answer lawfully rather than legally. This is called common law, and it came from Great Britain. France doesn't have it.
