“Hundreds” won’t be enough. Not by a long shot.
(Newser) – President Trump on Thursday again declared the situation at the US-Mexico border a "national emergency" and promised to get the military involved. Now it appears the Pentagon is preparing to do just that. Defense chief James Mattis is expected to sign an order authorizing at least 800 troops to head to the border, reports the AP. It wasn't immediately clear whether they'd be active-duty troops or members of the National Guard, or what their specific duties would be, reports CNN. But the best guess is that the troops would help shore up fencing and other barriers along parts of the border deemed vulnerable, rather than directly engaging with migrants attempting to cross illegally
