The viability of the Trump administration’s border wall has come under fire as all eight prototype structures have failed at least one breach test. The eight border wall prototypes in Otay Mesa, California were assembled in early 2017 after an executive order directed the Department of Homeland Security to build the border wall. The news comes as the administration prepares to potentially declare a national emergency to jumpstart construction of the wall along the U.S.’s southern border.
