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.

During his first term, Trump considered painting the border wall black to make it harder for illegal immigrants to climb during the summer.

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