"The entire wall along the U.S.-Mexico border will be painted black to make it hotter and deter illegal immigration," U.S. Secretary of Homeland Security Kristy Noem said during a visit to a fragment of the wall in New Mexico on Tuesday evening, August 19, CBS News reported.

Noem clarified that the decision to paint was made at the special request of US President Donald Trump, "who understands that in hot conditions, when something is painted black, it heats up even more, and it will be even more difficult for people to climb over the wall." The specific author of such an "idea" and the timing of the work are not specified. dw.com.

According to the minister, painting black over metal will discourage people on the other side of the border from illegally entering the United States. In turn, the head of the US Border Guard Service, Mike Banks, who also attended the event at the wall, expressed the opinion that the paint would also help prevent rust, CBS said.
