Giving credit to the idea to Donald Trump, Homeland Security Secretary Kristi Noem has said, the US-Mexico border wall will be painted black completely to make it hotter and harder to climb.
While domestic detentions and deportations have been the major focus of the current immigration crackdown, the policy bill by President Trump passed earlier this summer also made available $46m (£34m) for additional wall construction.
The Homeland Security Secretary said, about a half mile (0.8km) of wall is going up every day along the nearly 2,000 mile (3,218km) border.
In recent months, the number of border crossings has fallen and the Trump administration said, sweeping arrests and detentions are acting as a deterrent to illegal migration.
On Tuesday, Noem said that, the black paint was “specifically at the request of the President”.
She continued, the President “understands that in the hot temperatures down here, when something is painted black it gets even warmer and it will make it even harder for people to climb.”
