DHS informed Congress today that troops are going to spend the next month painting the border wall & “the primary purpose is to improve the aesthetic appearance.” A disgraceful misuse of taxpayer $$. Our military has more important work to do than making Trump’s wall beautiful. — Senator Dick Durbin (@SenatorDurbin) June 5, 2019

“A disgraceful misuse of taxpayer $$,” Durbin said on Twitter. “Our military has more important work to do than making Trump’s wall beautiful.”

CBS News reported that lawmakers were notified of the assignment via email. DHS said that an unspecified number of service members would paint barriers in Calexico, Calif., a city located along the southern border, according to text shared with the news network. The assignment will reportedly take about a month.

"While the primary purpose is to improve the aesthetic appearance of the wall, there may also be an operational benefit based on our experience with painted barrier in Nogales, Arizona," the email read, CBS News noted.

DHS and the Pentagon did not immediately return a request for comment from CBS News. The departments did not immediately respond to requests for comment from The Hill.

DHS pointed to the benefits of painting border structures in its notification to Congress, noting that painting border barriers in Tucson, Ariz., helped Border Patrol agents combat "camouflaging tactics of illegal border crossers" who tried to escape detection, CBS News reported. DHS added that migrants appear to have more difficulty climbing painted barriers.
