First impeachment inquiry into Andrew Johnson

The first impeachment inquiry into Andrew Johnson was launched by a vote of the United States House of Representatives on January 7, 1867, to investigate the potential impeachment of the President of the United States, Andrew Johnson. It was run by the House Committee on the Judiciary.

The vote authorizing the inquiry was viewed as giving Republicans an opportunity to register their disdain for Johnson without formally impeaching him. Most congressmen had expected that the sentiments in House Committee on the Judiciary would side against impeachment. However, surprising many, the committee voted 5–4 on November 25, 1867, to recommend impeachment (after having held a preliminary vote against it months prior). Despite this recommendation, the House voted 57–108 on December 7, 1867, against impeaching Johnson, with more Republicans voting against impeachment than for it.

This impeachment inquiry preceded the second impeachment inquiry into Andrew Johnson (launched in January 1868), which played a role in the lead-up to Johnson's impeachment on February 24, 1868.
