Impeachment proceedings may be commenced by a member of the House of Representatives on her or his own initiative, either by presenting a list of the charges under oath, or by asking for referral to the appropriate
committee. The impeachment process may be initiated by non-members. For example, when the
Judicial Conference of the United States suggests a federal judge be impeached, a charge of actions constituting grounds for impeachment may come from a
special prosecutor, the President, or
state or territorial legislature,
grand jury, or by
petition.
The type of impeachment
resolution determines the committee to which it is referred. A resolution impeaching a particular individual is typically referred to the
House Committee on the Judiciary. A resolution to authorize an investigation regarding impeachable conduct is referred to the
House Committee on Rules, and then to the Judiciary Committee. The House Committee on the Judiciary, by majority vote, will determine whether grounds for impeachment exist. If the Committee finds grounds for impeachment, it will set forth specific allegations of misconduct in one or more articles of impeachment. The Impeachment Resolution, or Article(s) of Impeachment, are then reported to the full House with the committee's recommendations.
The House debates the resolution and may at the conclusion consider the resolution as a whole or vote on each article of impeachment individually. A
simple majority of those present and voting is required for each article or the resolution as a whole to pass. If the House votes to impeach, managers (typically referred to as "House managers", with a "lead House manager") are selected to present the case to the Senate. Recently, managers have been selected by resolution, while historically the House would occasionally elect the managers or pass a resolution allowing the appointment of managers at the discretion of the
Speaker of the United States House of Representatives. These managers are roughly the equivalent of the prosecution/district attorney in a standard criminal trial.
Also, the House will adopt a resolution in order to notify the Senate of its action. After receiving the notice, the Senate will adopt an order notifying the House that it is ready to receive the managers. The House managers then appear before the bar of the Senate and exhibit the articles of impeachment. After the reading of the charges, the managers return and make a verbal report to the House.
