To the Senate of the United States:
On the 12th day of August, 1867, by virtue of the power and authority vested in the President by the Constitution and laws of the United States, I suspended Edwin M. Stanton from the office of Secretary of War.
In further exercise of the power and authority so vested in the President, I have this day removed Mr. Stanton from office and designated the Adjutant-General of the Army to act as Secretary of War ad interim.
Copies of the communications upon this subject addressed to Mr. Stanton and the Adjutant-General are herewith transmitted for the information of the Senate.
ANDREW JOHNSON.
