I don't see an issue with declaring a national emergency. The dems want de-facto open borders, that itself is unconstitutional, as are sanctuary cities/states. They swore to protect the US, and then do not allow the president to extend the wall and replace ineffective fences due to inadequate funding. Yet we protect borders in South Korea, Ukraine, Iraq, Poland, etc.
Those borders face actual threats...
No, "My Daughter might Date a Mexican" is not a national emergency.
Signing the Bill and then declaring a national emergency puts the issue to the courts to define presidential authority regarding emergencies and re-purposing approved funds. The many caravans coming up from Central America do present a clear and present danger to the US.
Actually, I think your tiny little brain hasn't thought this through at all. Let's say the Courts actually uphold Trump's position, that if you hysterically scream about a "problem" (not really) and call it a national emergency, he can override congress and the law.
Then in 2020, Trump and the GOP get voted out of office, and the new Democrat President declares "gun violence' a "National Emergency" (because it is killing far more people than undocumented immigrants being bad drivers are). The ATF then proceeds to go around confiscating guns because... National Emergency.
You boys didn't think this one through at all, did you?
