President Donald Trump signed his name on Wednesday on a newly constructed section of the US-Mexico border wall, calling it a “world-class security system” that will be virtually impenetrable.
Trump toured a section of the border wall in San Diego’s Otay Mesa area. It was a return trip for the president, who travelled there in March 2018 to see border wall prototypes that authorities later destroyed to make way for 14 miles (22.4 kilometres) of steel, concrete-filled bollards currently under construction.
Before construction began, the border in San Diego was protected by an initial layer of sheet metal that was easily blow-torched and a second, more formidable layer that could be compromised with powerful, battery-operated saws.—AP
