The impeachment proceedings against President Andrew Johnson in 1868 resulted in his acquittal. He was impeached by the House of Representatives primarily for violating the Tenure of Office Act by removing Edwin M. Stanton from his position as Secretary of War and attempting to replace him. The case then moved to the Senate, where a trial was held.
The Senate ultimately voted on the articles of impeachment, and Johnson was acquitted by a narrow margin. The final vote was 35 guilty to 19 not guilty, which fell one vote short of the two-thirds majority required for conviction. As a result, Johnson remained in office and completed his presidential term. This impeachment was significant as it marked the first time a U.S. president was impeached, setting a precedent for future proceedings.
