Criticism has arisen from legal experts regarding a potential expansion of military involvement in domestic matters. A memo from the Department of Homeland Security discusses using National Guard troops for certain tasks. This document was obtained through a Freedom of Information Act request.

The memo outlines specific situations in which troops could take on new roles. It suggests that Guard members could be designated in certain ways if deployed across state lines.

Further details about the memo and its implications are available from the source, including the circumstances under which troops could perform new functions and the potential consequences of such actions.
