The D.C National Guard was formed in 1802 by President Thomas Jefferson to defend the newly created District of Columbia. As such, the Commanding General of the D.C. National Guard is subordinate solely to the President of the United States. This authority to activate the D.C. National Guard has been delegated, by the President, to the Secretary of Defense and further delegated to the Secretary of the Army. The D.C. National Guard is the only National Guard unit, out of all of the 54 states and territories, which reports only to the President.
