Washington, March 14: US President Dold Trump has inspected prototypes for his long-promised wall along the border with Mexico in a tour that drew both supporters and protesters. “If you don’t have a wall system here, we’re not gon have a country,” Trump warned while touring the eight prototypes of the wall he promised to build to keep out illegal immigrants near San Diego in the state of California. His inspection on Tuesday, of the prototypes made of concrete, steel and other materials marks his first visit to California since assuming office, Xinhua news agency reported. He is also the first president since Dwight Eisenhower to skip a visit to the “Golden State” during the first year in office.
