Message To Congress

Washington, January 2, 1863

TO THE SENATE AND HOUSE OF REPRESENTATIVES:

I submit to Congress the expediency of extending to other departments of the government the authority conferred on the President by the eighth section of the act of the 8th of May, 1792, to appoint a person to temporarily discharge the duties of Secretary of State, Secretary of the Treasury, and Secretary of War, in case of the death, absence from the seat of government, or sickness of either of those officers.

A. LINCOLN.
