This bill amends federal law to impose new requirements on the President regarding the domestic deployment of National Guard members. It mandates that the President provide Congress with a 24-hour advance notification before federalizing the National Guard for domestic service, detailing the specific justification for the deployment. The required notice must include a good-faith claim explaining the nature of the invasion, rebellion, or inability to execute laws, along with the geographical area, expected duration, and the training received by units interacting with civilians. It also requires disclosure of the chain of command and communication protocols with state and local forces. Furthermore, for deployments lasting longer than 48 hours, the President must provide written updates to Congress every 72 hours , asserting the continued necessity and describing any changes to the deployment conditions.
