Trump’s border wall with Mexico faces all kinds of obstacles

WASHINGTON (AP) — President Donald Trump has now laid out exactly what he wants in the “big, beautiful wall” that he’s promised to build on the U.S.-Mexico border. But his effort to build a huge barrier to those attempting to enter the U.S. illegally faces impediments of its own.
It’s still not clear how Trump will pay for the wall that, as described in contracting notices, would be 30 feet (9 meters) high and easy on the eye for those looking at it from the north.
