As a candidate, Trump promised to build an “impenetrable, physical, tall, powerful, beautiful” wall on the border that would be paid for by Mexico.
….The Trump administration directed the construction of eight steel and concrete prototype walls that were built in Otay Mesa, California, just across the border from Tijuana, Mexico. …Trump settled on a steel slat, or steel bollard, design for the proposed border barrier additions. Steel bollard fencing has been used under previous administrations.
A photo exclusively obtained by NBC News shows the results of the test after military and Border Patrol personnel were instructed to attempt to destroy the barriers with common tools.
While it is true that previous administrations used this design, the prototype was built during his administration.
