Leaked DHS Memo Reveals Potential Use of Military to Enforce Immigration At U.S. Borders and Inside Cities

A leaked Department of Homeland Security memo authored by Philip Hegseth, a senior adviser at DHS, suggests the U.S. government may soon deploy the military more frequently to enforce immigration laws — not just at the southern border, but also in major U.S. cities.

First reported by The New Republic on August 2, 2025, the memo outlines a proposal urging the Pentagon to treat immigration enforcement as a higher operational priority.

It specifically notes potential operations in urban centers such as Los Angeles, signaling a shift from traditional border-focused deployments to broader domestic involvement.

Under President Donald Trump, military participation in immigration enforcement has already reached unprecedented levels.

Past measures have included:

  • Thousands of active-duty troops stationed at the southern border
  • Military aircraft used for deportations, with widely circulated images showing migrants being escorted onto planes
  • Deployment of the National Guard and Marines to Los Angeles during periods of civil unrest

If the recommendations in Hegseth’s memo move forward, immigration enforcement could see an even deeper military integration — a move likely to fuel both legal and political debate over the use of armed forces in domestic law enforcement.
