Question

Quizplus · Accepted Answer

While the president has the authority to order the National Guard to deploy for federal missions overseas or in support of federal law enforcement agencies, the Posse Comitatus Act prohibits the use of the military, including the National Guard, for law enforcement activities within the United States. Governors have the authority to activate and deploy National Guard troops within their own states for certain domestic missions.
