The wall along the southern border will be painted black in an effort to make the structure too hot to climb, Department of Homeland Security Secretary Kristi Noem announced Tuesday, saying the suggestion came from President Donald Trump.

Homeland Security Secretary Kristi Noem says the entire southern border wall with Mexico is being painted black to deter illegal immigration, at President Trump's request.

This isn't the first time Trump has used this exact strategy. In 2019, he ordered that segments of the wall be painted black to make them hotter. However, when The Washington Post visited a section of the wall near Sasabe, Ariz., in March 2022 — less than 18 months after it was applied — the paint was already peeling off.
