One of President Donald Trump's biggest campaign promises was that he was going to build a wall between the U.S. and Mexico.
The wall will cost a reported $21.6 billion dollars, which many are criticizing as excessive, due to the fact that cuts for way less have been made to the EPA, Meals on Wheels, the NEA, and other food and care programs. Not to mention the fact that walls don't necessarily have a good track record when it comes to being, you know, effective.
Trump's stance since declaring he'd build the wall has been that Mexico will ultimately end up paying for it. Shortly after he was elected, however, it was revealed that Congress would be paying for the wall, not Mexico, something that Trump's critics have been saying for a while.
