Trump touts progress on border wall prototypes

President Trump tweeted on Tuesday that construction of prototypes for his long-promised wall along the U.S.-Mexico border is “underway.”

“BORDER WALL prototypes underway!” Trump tweeted, along with a short video of construction teams and cranes raising large concrete slabs along the southern border.

Eight prototypes of the wall, a trademark campaign promise of Trump’s as a way to halt illegal immigration, are currently being erected near San Diego in southern California. 

The U.S. Customs and Border Patrol agency in San Diego has posted several photo updates on the construction of the wall models, built by several construction companies with various defensive features.
