Answer:
The U.S. House of Representatives votes 11 articles of impeachment against President Andrew Johnson, nine of which cite Johnson’s removal of Secretary of War Edwin M. Stanton, a violation of the Tenure of Office Act. The House vote made President Johnson the first president to be impeached in U.S. history.
Step-by-step explanation:
On February 21, 1868, Johnson decided to rid himself of Stanton once and for all and appointed General Lorenzo Thomas, an individual far less favorable to the Congress than Grant, as secretary of war. Stanton refused to yield, barricading himself in his office, and the House of Representatives, which had already discussed impeachment after Johnson’s first dismissal of Stanton, initiated formal impeachment proceedings against the president. On February 24, Johnson was impeached, and on March 13 his impeachment trial began in the Senate under the direction of U.S. Supreme Court Chief Justice Salmon P. Chase. The trial ended on May 26 with Johnson’s opponents narrowly failing to achieve the two-thirds majority necessary to convict him.
