The purpose of this legislation is to grant the Mayor of the District of Columbia the same authority over the National Guard that governors of U.S. states have over their respective National Guards. This includes the ability to manage the National Guard and deploy it in response to emergencies such as natural disasters and civil disturbances. Key provisions of the legislation include changes to existing laws that replace references to the "President of the United States" with "Mayor of the District of Columbia" in various sections related to the National Guard.
