The first impeachment inquiry against Andrew Johnson was launched by a vote of the United States House of Representatives on January 7, 1867 to investigate the potential impeachment of Andrew Johnson, the president of the United States. It was run by the House Committee on the Judiciary. This impeachment inquiry preceded the second impeachment inquiry against Andrew Johnson (launched in January 1868), which played a role in the lead up to the February 24, 1868 impeachment of Johnson.
