Trump calls new border wall a 'world-class security system'
President Donald Trump signed his name on a newly constructed section of the U.S.-Mexico border wall (which replaced a previous wall), calling it a world-class security system that will be virtually impenetrable. Trump toured a section of the border wall in San Diegos Otay Mesa area on Wednesday. Its the Rolls-Royce version, Trump said.
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.
Trump said cost concerns led him to put aside his preference to paint the wall black. He said the wall was a good, strong rust color.
When Trump asked Army Corps Lt. Gen. Todd Semonite to explain how technology embedded in the wall alerts agents to illegal activity,
he was told,
Sir, there could be some merit in not discussing it. We don't want to tell them how to defeat it."
