So Trump is calling a national emergency to get the military to build his border wall for him.
There seems to be little the Congress or anybody else can do to step him.
So my question is .... why didn't he just do that before?? It's been 2+years of border wall negotiations. If he could bypass it so easily, why wait until now?
In fact, doing it as soon as possible would also lend more weight to the idea that it is an emergency, no?
I have heard people saying it's a "measure of last resort" .... but why?.
