Trump wants to paint border wall black so it’s too hot for would-be migrants to touch

WASHINGTON – US President Donald Trump has ordered the entire southern border wall to be painted black to stop would-be migrants from crossing because it will be too hot to touch, according to Homeland Security Secretary Kristi Noem.

Speaking near the border in New Mexico on Aug 19, Ms Noem said crews have begun painting sections of the 9m steel bollards that make up the barriers.

She said the directive came directly from Mr Trump, under the expectation the dark paint will extend the steel’s lifespan by slowing rust and discourage would-be migrants to climb the wall by making it unbearably hot under the desert sun.

“We are going to be painting the entire border wall black,” Ms Noem told reporters.

Asked about criticism that the practice could make conditions harsher for would-be migrants, she responded: “Don’t touch it. People have a choice.”

Ms Noem did not say how much the project will cost or how long it will take.

She applied paint herself to a small section of a fence during the media appearance in Santa Teresa, New Mexico.

Ms Noem’s visit came as arrests at the south-west border have plunged to levels not seen in decades – as the administration enacts stricter enforcement measures.

It has also shut down the CBP One mobile app that had previously been a key way for would-be migrants to schedule appointments to cross the border and seek asylum.

Mr Walter Slosar, the interim chief patrol agent in the El Paso Sector, covering far West Texas and all of New Mexico, said the current seven-day arrest average is about 41 a day, with an additional nine migrants crossing daily without being stopped.

A year ago the average was closer to 400 a day, and it was roughly 2,300 in 2023. 

Still, the administration has pressed ahead with wall construction, filling in gaps in Santa Teresa, where about 11km of new barriers are being installed.

Mr Trump’s plan to build out a southern border wall has long been a lightning rod, dating back to Mr Trump’s first term when his administration added razor wire to some sections, while painting some areas black, but ultimately built far fewer kilometres of new barriers than initially promised.

Despite that, Mr Trump has kept the wall central to his immigration message, portraying it as a tool of enforcement.

Congress in July approved a budget Bill that set aside almost US$47 billion (S$60.4 billion) for continued border wall construction and maintenance, giving the administration a new stream of money to carry forward Mr Trump’s plans.

The clampdown is visible across the desert region.

In Sunland Park, New Mexico, residents can see a Stryker armoured combat vehicle perched on a mesa overlooking Mexico, an American flag fluttering from its rear.

Border Patrol agents and military personnel patrol the area, part of an arrangement that has thousands of active-duty troops deployed under US Northern Command.

The troops have been authorised to briefly detain and search migrants in newly designated National Defence Areas near the boundary, which the Pentagon says are effectively extensions of US military installations. BLOOMBERG
