Thaddeus Stevens delivers the last speech to Congress
about the impeachment of President Andrew Johnson.

The U.S. House of Representatives voted 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.

   
Edwin McMasters Stanton
(December 19, 1814 – December 24, 1869)
