More Information About How President Trump Will Make Mexico Pay for the Wall

I am not sure if "the wall" will stop drugs as the Mexican drug cartels have many tunnels. However President Trump promised the wall and he does keep his promises, or at least try's to. It is interesting to read the comments of this video and see the votes are 4  negatives to 1 positive. I want to learn what the Trump administration is doing regardless if I think it will be a good investment or not.
