Nothing on the Sec. of the Army's website though.
Miltary Times:
“The 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,” according to the Army official. “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. In this status they operate similar to a state National Guard unit in Title 32 status with the same legal authorities.”
