The article says that the language in the constitution is for birthright citizenship, but the conservatives will try to make some sort of stupid nuanced argument to create a loophole that kick kids of undocumented immigrants out of the country.
But if Trump were to try to use executive action to eliminate birthright citizenship, courts would probably strike it down because of language contained in the 14th amendment, according to scholars.
Still, given the conservative majority on the supreme court – and fact that one of the people considered a candidate for the court has argued that the provision does not apply to children of “invading aliens” – it’s not a certainty that birthright citizenship will remain in place, said Amanda Frost, a University of Virginia law professor and expert in immigration and citizenship law.

If the scotus allowed this, this would be an epic clusterfuck across the nation. If you’re the kid of undocumented immigrants and your citizenship is no longer valid, how about your kids? How about your kids kids?
This would be such a fucking shit show.
