US military expected to announce two new zones where service members can detain migrants on southern border, officials say
- The Pentagon announced on July 2, 2025, the creation of two new National Defense Areas where U.S. troops can detain migrants along the southern border in Texas and Arizona.
- These new zones follow President Trump's April 11, 2025, memorandum directing the military to seal the border amid his 2024 immigration crackdown and re-election campaign focus.
- The Texas National Defense Area, managed through Joint Base San Antonio, encompasses approximately 250 miles of the Rio Grande, while the zone adjacent to Marine Corps Air Station Yuma in Arizona covers more than 100 miles.
- Only four detentions have occurred in the zones so far, with 120 trespassing convictions in Texas and the first two convictions in New Mexico reported in mid-2025.
- The zones aim to enhance border security without invoking the 1807 Insurrection Act, but they remain controversial and have faced legal challenges and political criticism.
