1868 – U.S. President Andrew Johnson was acquitted during the Senate impeachment, by one vote

The first Senate vote in the impeachment of President Andrew Johnson was taken on May 16, 1868. Article XI was called the “omnibus article” because it combined all of the charges against the President. As a result of 19 voting “Not Guilty” and 35 voting “Guilty,” the Senate fell 1 vote short of the two-thirds majority required for removal. After a 10-day recess, the Senate reconvened and voted on Articles II and III. In each case, the result was identical: Johnson was not guilty by a single vote. The Senate then voted to end the trial.

In the 1868 Johnson impeachment trial, the embattled president was just one vote away from being removed from office on each of the three charges put to a vote. There were 11 total articles of impeachment, but the Senate voted to adjourn the trial when it was clear that the voting would be the same for each remaining charge.
