Donna, Texas was the site of a military encampment for troops supporting the Border Patrol in late 2018.
Thousands of National Guard troops who have rotated to the southern border since 2018 are supposed to head home by the end of September. But the Department of Homeland Security wants the border mission to continue.
President Joe Biden announced in February that he would rescind the Trump administration's national emergency declaration on the U.S.-Mexico border, which took effect in 2019. It had allowed National Guard and reserve troops to support counterdrug operations and provide engineering, logistics and other aid to Customs and Border Protection.
