Tariffs on goods coming in from MX and taxing remittances that go out to MX.
And Trump is going to get Congress, the Democrats and the Establishment that WANTS open borders and Amnesty to agree to tax and impose tariffs on Mexico to pay for Trumps wall?
Or do you expect Trump to simply decree a wall built and contractors make it so after the DOJ sued states to prevent them to enforce laws that are now suspended?
And what happened to the 1.2 billion in funds appropriated in the 2006 Secure Border Act that Congress passed??
What concrete viable steps does Trump have to ensure that his wall will get built beyond his mere words should Congress actually pass another build-a-wall bill?
