The President has made this false claim before.Trump long ago abandoned his 2016 campaign promise that Mexico would pay to build a wall. Instead, he now makes the case that Mexico will “indirectly” pay for the barrier, thanks to the potential increase in tax revenue generated by his replacement for the North America Free Trade Agreement.
But the new deal hasn’t yet been ratified by Congress, where Democrats have expressed opposition. And even if the new United States Mexico Canada Agreement ends up raising tax revenue, there’s nothing earmarking that money for a wall. Income and corporate taxes are general revenue that would have to be appropriated by Congress.
Another way trade could bring money into the Treasury is through tariffs — which are paid by American importers when they buy foreign goods. But like the original NAFTA, the new deal aims to keep trade between the three countries largely tariff-free.
This is overstated. Available Customs and Border Protection data shows a total of 396,579 people were apprehended by the US Border Patrol for fiscal year 2018 at the southwest border, which would mean an average of 1,087 each day — hardly the “thousands” that Trump purports. The numbers differ each month. The highest number of apprehensions was in September, with a daily average of nearly 1,400.
Apprehensions are still well below historic highs. In the early 2000s, for example, annual apprehensions routinely topped 1 million. After hitting an historic low in 2017 of around 300,000, apprehensions increased in fiscal year 2018 to nearly 400,000.
