A. Johnson broke the law when he fired Secretary of War Edwin Stanton without Congressional approval. B. Southern Democrats felt Johnson made it too difficult for them to rejoin the Union.
Explanation:
After the assassination of Lincoln in the spring of 1865, Johnson became president. However, his policy was significantly different from the line pursued by his predecessor - in particular, he vetoed the law almost unanimously adopted by Congress on the return of Southern States to the Union of and blacks’ civil equality. The president had a long conflict with Congress, including because of an attempt to fire the Secretary of War. The president dismissed Edwin Stanton several times, but the Senate each time found the grounds for dismissal insufficient and reinstated him. Therefore, the House of Representatives began the impeachment process in 1868 and most of its representatives voted in favor of it.
