National Guard Proper Use Act

HR 5604, the National Guard Proper Use Act, prohibits military and National Guard personnel from being ordered to enforce federal immigration laws. It adds new sections to military law (Title 10 for active forces and Title 32 for the National Guard), explicitly stating members cannot be directed to perform duties related to immigration enforcement. This directly affects military commanders who might attempt to assign such tasks and ensures National Guard members remain focused on their core missions, not civilian immigration enforcement. The bill references the Posse Comitatus Act (18 U.S.C. §1385), a longstanding law that limits military involvement in domestic law enforcement. It clarifies existing legal boundaries without creating new programs or funding.
