The Trump administration is painting the U.S.-Mexico border fence black to make the steel so hot migrants won't climb it. Homeland Security Secretary Kristi Noem unveiled the plans Aug. 19 in a news conference in Santa Teresa, New Mexico, while workers ran paint rollers up the steel bollards behind her.

The Defense Department has established the Mexican Border Defense Medal for U.S. troops who have deployed to the southern border since Jan. 20 to support agents with U.S. Border and Customs Protection, or CBP, according to a Pentagon memo shared on social media.

Soldiers are using U.S.-Mexico border deployments as a chance to try out new technology, including a reworked version of IVAS headsets.
