This seems kind of odd. It won't affect very many people. It sort of feels like a solution to a problem that doesn't really exist. Maybe Trump feels like this gets him one step closer to ending birthright citizenship.
I think it’s an attempt changing the news cycle from the trade war and recession situation.
Sarmucci described trump best: people aren’t people. They are either obstacles or stepping stones.
When looking at trumps actions in that light, it becomes clear he’s throwing peoples lives into chaos to avoid his own embarrassments. It’s a really bad version of house of cards.
