https://www.nytimes.com/2018/04/03/us/politics/trump-border-immigration-caravan.html“We have very bad laws for our border, and we are going to be doing some things — I’ve been speaking with General Mattis — we’re going to be doing things militarily,” Mr. Trump said at the White House, seated beside the defense secretary at a meeting with visiting leaders of Baltic nations. “Until we can have a wall and proper security, we’re going to be guarding our border with the military. That’s a big step. We really haven’t done that before, or certainly not very much before.”
Trump claims that a dysfunctional congress has made this action necessary for the defense of the country against drug cartels, gangs, potential terrorism, and many other problems stemming from illegal immigration.
