Well let's get right to the facts.
Fact: the US is not losing undocumented / illegal immigrants at an abnormally high rate. That's a myth. Trump has hardly moved the needle at all when it comes to illegal immigration. Everything to the contrary is propaganda pushed by the media for pathetic political points / ratings.
Obama deported more people in an average year than Trump has in his first year. He was known in immigration circles as the deporter in chief for it.
