Impeachment article:
Officials subject to impeachmentThe central question regarding the Constitutional dispute about the impeachment of members of the legislature is this:
Are members of Congress "officers" of the United States? The Constitution grants to the House the power to impeach "The President, the Vice President, and all civil Officers of the United States." [2] Many believe firmly that Members of Congress are not "officers of the United States." [5]. Others, however, believe that Members are civil Officers and are subject to impeachment.
The
House of Representatives did impeach a Senator once[6], Senator William Blount. The senate expelled Senator Blount and, after initially hearing his impeachment, dismissed the charges for lack of jurisdiction[7]. Left unsettled was the question "Are members of Congress civil officers of the United States?" The House has never impeached a Member of Congress after Blount and, as each House has the authority to expel their own members—without involving the other chamber; expulsion has been the method used for removing Members of Congress.
Jefferson's Manual, which is integral to the House rules, states that impeachment is set in motion by: charges made on the floor; charges preferred by a memorial; a Member's resolution referred to a committee; a message from the President; charges transmitted from the legislature of a State or territory or from a grand jury; or from facts developed and reported by an investigating committee of the House. It further states that a proposition to impeach is a question of high privilege in the House and at once supersedes business otherwise in order under the rules governing the order of business.
