Which President was impeached and narrowly avoided removal from office?

Andrew Johnson was the President who was impeached and narrowly avoided removal from office. He faced impeachment in 1868 primarily due to his violation of the Tenure of Office Act, which was a law intended to restrict the president's power to remove certain office-holders without the Senate's approval. The House of Representatives approved articles of impeachment against him, making him the first president in U.S. history to be impeached.

During the subsequent Senate trial, Johnson was acquitted by just one vote, which highlighted the deep political divisions of the time and the complexities of the impeachment process. This narrow margin prevented his removal from office, allowing him to serve the remainder of his term. His presidency was marked by significant conflicts with Congress, particularly regarding the reconstruction of the South after the Civil War.

In contrast, the other Presidents listed did not face impeachment proceedings; they either completed their terms or served under different circumstances that did not involve such a significant political challenge.
