Homeland Security Secretary Kristi Noem says the entire southern border wall with Mexico is being painted black to deter illegal immigration.

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.

President Donald Trump ordered the entire southern border wall to be painted black to stop migrants from crossing because it’ll be too hot to touch, according to Homeland Security Secretary Kristi Noem.
