This bill proposes amendments to title 32, United States Code, to clarify limitations on full-time National Guard duty performed within a State, Territory, or the District of Columbia, particularly when supporting federal operations. It mandates that such deployments, requested by the President or Secretary of Defense , require the explicit consent of the relevant local authority. Specifically, approval must be obtained from the chief executive officer of each State where operations occur, or from the Mayor of the District of Columbia if the mission takes place there. Furthermore, the bill explicitly states that any training or duty ordered under these provisions must adhere to the restrictions outlined in the Posse Comitatus Act , reinforcing limitations on military involvement in civilian law enforcement.
