Solution:Andrew Johnson was the 17ᵗʰ President of the United States, serving from 1865 to 1869. He faced impeachment by the House of Representatives in 1868, primarily due to his violation of the Tenure of office Act by removing Edwin M. Stanton, the Secretary of War.
The Impeachment proceedings were highly contentious and he was acquitted by the Senate by just one vote, allowing him to remain in office.
