Kristi Noem Confirms Black Paint for Southern Border Wall/ Newslooks/ WASHINGTON/ J. Mansour/ Morning Edition/ Homeland Security Secretary Kristi Noem announced that the entire southern border wall will be painted black, a directive she credited to President Trump. Officials say the black paint will make the steel hotter, deterring migrants from climbing it, while also reducing rust. The move comes as the Trump administration accelerates wall construction with $46 billion in new funding.

Deep Look: Trump’s Border Wall to Be Painted Black in New DHS Move
Homeland Security Secretary Kristi Noem confirmed the plan Tuesday during a visit to a stretch of wall in New Mexico. With paint roller in hand, she joined workers in applying the first coats. Noem credited the initiative directly to President Donald Trump, who she said suggested the color change as part of his broader immigration deterrence strategy.
Making the Wall Hotter — and Harder to Climb
Noem explained the reasoning behind the color shift: “When something is painted black in high desert heat, it absorbs more warmth. That makes the steel hotter, making it more difficult for individuals to climb.”
She added that the wall’s sheer height and depth already serve as major obstacles, but painting it black would add another deterrent layer.
U.S. Border Patrol Chief Mike Banks, appearing with Noem, also pointed out a secondary benefit: the black paint could help reduce rust and corrosion along the nearly 2,000-mile barrier.
Trump’s Immigration Priorities
During his first presidency, Trump made building the wall the centerpiece of his immigration agenda. In his second term, attention has shifted toward mass deportations and interior enforcement — but completing the wall remains a priority.
Congress this summer approved $46 billion in new DHS funding to accelerate border construction. Noem said that under current efforts, crews are building half a mile of barrier each day.
“The wall will look very different depending on where it is built,” she said, noting that topography and geography — deserts, mountains, and rivers — all affect design.
Extending the Wall Over Water
In addition to land barriers, DHS is working on water-borne infrastructure. Much of the Texas border runs along the Rio Grande, where wall construction requires unique adaptations.
“The department is expanding beyond land-based fencing,” Noem explained. “We are also making sure water crossings are reinforced where necessary.”
Political Symbol and Practical Tool
Painting the wall black may seem symbolic, but Noem emphasized that it was part of a serious enforcement strategy supported by Trump. The administration argues that tougher border barriers are helping to drive down illegal crossings, which have plummeted in recent months.
The move also highlights how Trump continues to shape immigration policy through visual and symbolic measures that reinforce his political brand. The border wall, already a physical embodiment of Trump’s approach, will now be marked with a color meant to amplify its deterrent effect.
The Bigger Picture
Even as deportations and enforcement dominate headlines, the wall remains a touchstone for Trump’s supporters. Noem said the administration is determined to complete it:
“The message is simple: Do not come illegally. This is about national security and the safety of the American people.”
