 Republicans in Congress, refusing to accept Johnson's lenient terms, rejected and refused to seat new members of Congress, some of whom had been high-ranking Confederate officials a few months before.Johnson broke with the Republicans after vetoing two key bills that supported the Freedmen's Bureau and provided federal civil rights to the freedmen.The 1866 Congressional elections turned on the issue of Reconstruction, producing a sweeping Republican victory in the North, and providing the Radical Republicans with sufficient control of Congress to override Johnson's vetoes and commence their own "Radical Reconstruction" in 1867.
