Criticism has arisen from legal experts regarding a potential expansion of military involvement. A memo from the Department of Homeland Security outlines scenarios where National Guard troops could take on immigration roles. This document was obtained through a Freedom of Information Act request.

The memo discusses the status of Guard members when deployed across state lines, suggesting they could be considered federal employees. Further details about this proposal are available.

The revelation of this memo has prompted concern about the limits of federal law and domestic policing. More information can be found through the source that obtained the document.
