President Donald Trump has signed his name on a newly constructed section of the US-Mexico border wall, calling it a “world-class security system” that will be virtually impenetrable.
Mr 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 of steel, concrete-filled bollards currently under construction.
You can fry an egg on that wallDonald Trump
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.
“It was like a sheet metal and people would just knock it over like just routinely,” Mr Trump said, referring to the initial layer that was replaced.
He stood with construction workers and top border protection, army and homeland security officials.
Mr Trump highlighted features of the wall, which he said have been studied by three other countries.
He said the wall absorbs heat -“You can fry an egg on that wall” – the concrete goes deep into the ground to prevent tunnelling and agents can see through it to spot possible threats on the Mexican side of the border, he said.
It's the Rolls-Royce version
“When the wall is built, it will be virtually impossible to come over illegally, and then we’re able to take border control and put them at points of entry,” Mr Trump said.
He heaped praise on the Mexican government, especially for sending tens of thousands of troops to its northern and southern borders to help slow the flow of migrants headed toward the United States.
He said President Andres Manuel Lopez Obrador “has been great”.
“We’re all thrilled,” Mr Trump said. “You know Mexico has never done anything to impede people from pouring into our country and now they’re doing just the opposite. They’ve really been incredible.”
The president said border patrol and military officials persuaded him to adopt more expensive designs for the wall.

He said he dropped a preference for solid concrete, instead opting for concrete-filled steel bollards that allow agents to see through to Mexico to spot assailants throwing rocks or other projectiles.
Mr Trump agreed to barriers that are 30 feet high and double-layered in heavily travelled areas.
“It’s the Rolls-Royce version,” he said.
When Mr 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.”
Mr Semonite offered new details on the pace of construction that underscored how quickly the administration plans to move.
It has built 66 miles so far, has 251 miles in various stages of construction at 17 sites and contracts for 163 miles planned in the next 90 days, the general said. Additional land on private property is expected to take more time.
Last week, the Supreme Court gave Mr Trump a green light to deny asylum to anyone who passes through another country on the way to the US border with Mexico without having first sought protection in the third country.
The Pentagon recently diverted $3.6 billion from 127 military construction projects to build 175 miles of barriers on the border.
Mr Trump had promised during the 2016 presidential campaign that Mexico would pay for the wall.
