Having said that, I will say I agree with Kim Wehle’s statement on Trump declaring a national emergency:

Unable to strong-arm Democrats into a $5.7 billion appropriation of his choosing, the president has threatened to leapfrog over Congress by declaring a national emergency to build the “wall” he promised his voter base.

For the umpteenth time during his presidency, the question arises: Can he legally do that?

For the umpteenth time, the answer is: It’s the wrong question. The right question is, if Trump declares a national emergency over the alleged “crisis” at the border, will there be any adverse consequences? Without enforcement, the Constitution and related laws are not worth the parchment they were written on.
