Whether or not it's a 14th ammendment issue is up for debate (apparently the people who chose the wording did so intentionally to prevent it from applying to Native Americans).

However, Constitutional or not, this entire thing is bullshit. He is looking for excuses to question the citizenship of anyone who he doesn't deam American enough. :/

Whether what they are calling "birthright citizenship" is removed via EO or legislation (I am pretty sure one or the other will happen if they aren't stopped somehow) it will make its way to the Supreme Court, where it may or may not be overturned. :/

So, whether it violates the 14th Amment or not, it is still Facism in action. It is still an unexcusable act. It is something that violates the very idea of what most of us think of as American values. :/
