Johnson did technically violate the Tenure of Office Act, which denied him the power to dismiss presidential appointees without the Senate's permission. This act was designed to protect Edwin M. Stanton, the Secretary of War under president Lincoln who had been held over in Johnson's cabinet. | When Johnson tried to fire the Secretary of War, the House, lead by Radical Republican [[Thaddeus Stevens]], impeached him.
