President Donald Trump wants to use the military to secure the US-Mexico border until his promised wall is built.
Mr Trump said during a lunch with Baltic leaders that he has spoken with Defence Secretary Jim Mattis about the idea.
He called it a “big step”.
Mr Trump begrudgingly signed a spending bill last month that provided far less money for the wall than he wanted.
The big Caravan of People from Honduras, now coming across Mexico and heading to our “Weak Laws” Border, had better be stopped before it gets there. Cash cow NAFTA is in play, as is foreign aid to Honduras and the countries that allow this to happen. Congress MUST ACT NOW!

He has been complaining that US borders are too porous and immigration laws are too weak.
