Abraham Lincoln vetoed the Wade-Davis Bill of 1864 because he felt it imposed a harsh punishment on the Confederate states that rebelled from the Union. Radical Republicans proposed the bill to punish the Southern states during the Reconstruction phase after the Civil War ended.
Through the pocket veto, Abraham Lincoln vetoed the bill that both the House of Representatives and the Senate passed. President Lincoln was in favor of a more lenient path for the Southern States, and he favored the 10 Percent Plan that he conceived during the war. Part of the plan stipulated that 10 percent of voters from the seceded states swear an oath of loyalty to the Union. It also pardoned Confederates who took part in the war.
