Impeachment in the United States

In the United States, impeachment is the process by which a legislature may bring charges against an elected member of the executive branch or an appointed official for severe alleged misconduct, and may result in removal of the guilty from their position after the consequential trial. In addition to Congress at the federal level, impeachment may occur at the state level if the state or commonwealth has provisions for it under its constitution. Impeachment might also occur with tribal governments as well as at the local level of government. Separate procedures are in place for elected members of the legislature to remove a peer for a comparable level of misconduct.

The federal House of Representatives can impeach a party with a simple majority of the House members present or such other criteria as the House adopts in accordance with Article One, Section 2, Clause 5 of the United States Constitution. This triggers a federal impeachment trial in the United States Senate, which can vote by a two-thirds majority to convict an official, removing them from office. The Senate can also vote to bar an individual convicted in a senate impeachment trial from holding future federal office with a simple-majority vote.

Most state legislatures can impeach state officials, including the governor, in accordance with their respective state constitution. A number of organized United States territories do as well. Additionally, impeachment is a practice of other government bodies, such as tribal governments.

Impeachment proceedings are remedial rather than punitive in nature, and the remedy is limited to removal from office. Because the process is not punitive, a party may also be subject to criminal or civil trial, prosecution, and conviction under the law after removal from office. Also because the conviction is not a punishment, the president of the United States is constitutionally prevented from granting a pardon to impeached and convicted persons, that may have protected them from the consequences of a conviction in an impeachment trial.

Federal impeachment

Constitutional provisions

Article I, Section 2, Clause 5 of the United States Constitution provides:

The House of Representatives shall choose their Speaker and other Officers; and shall have the sole Power of Impeachment.

Article I, Section 3, Clauses 6 and 7 provide:

The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two-thirds of the Members present. Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States; but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.

Article II, Section 2 provides:

[The President] ... shall have power to grant reprieves and pardons for offenses against the United States, except in cases of impeachment.

Article II, Section 4 provides:

The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.

The Constitution limits grounds of impeachment to "Treason, Bribery, or other high Crimes and Misdemeanors", but does not itself define "high crimes and misdemeanors".

The Constitution gives Congress the authority to impeach and remove "The President, Vice President, and all civil Officers of the United States" upon a determination that such officers have engaged in treason, bribery, or other high crimes and misdemeanors. The Constitution does not articulate who qualifies as a "civil officer of the United States". Federal judges are subject to impeachment. Within the executive branch, any presidentially appointed "principal officer", including a head of an agency such as a secretary, administrator, or commissioner, is a "civil officer of the United States" subject to impeachment. At the opposite end of the spectrum, lesser functionaries, such as federal civil service employees, do not exercise "significant authority", and are not appointed by the president or an agency head. These employees do not appear to be subject to impeachment, though that may be a matter of allocation of House floor debate time by the Speaker, rather than a matter of law.

The Senate has concluded that members of Congress (representatives and senators) are not "civil officers" for purposes of impeachment. As a practical matter, expulsion is effected by the simpler procedures of Article I, Section 5, which provides "Each House shall be the Judge of the Elections, Returns and Qualifications of its own Members ... Each House may determine the Rules of its Proceedings, punish its Members for disorderly Behavior, and, with the Concurrence of two thirds, expel a Member" (see List of United States senators expelled or censured and List of United States representatives expelled, censured, or reprimanded). This allows each House to expel its own members without involving the other chamber. In 1797, the House of Representatives impeached Senator William Blount of Tennessee.

The constitutional text is silent on whether an officer can be tried after the officer resigns or their term ends. However, when the issue has arisen, the House has been willing to impeach after resignation, and the Senate has been willing to try the official after resignation. In 1797, the Senate continued impeachment proceedings against William Blount even after he had been expelled from office, dismissing the proceedings only after determining that a Senator is not a "civil officer of the United States". In 1876, William W. Belknap was impeached by the House of Representatives hours after resigning as United States Secretary of War. The Senate held by a 37–29 vote that it had jurisdiction to try Belknap notwithstanding his resignation, but ultimately acquitted him after trial. The permissibility of trying a former official was a major issue in the second impeachment trial of Donald Trump, which commenced twenty days after Trump's term in office expired, although Trump's impeachment itself occurred while he was president. By a 55–45 vote, the Senate rejected a motion asserting that the trial was unconstitutional.

The Constitution does not limit the number of times an individual may be impeached. As of 2025, Donald Trump is the only federal officer to have been impeached more than once.

Process

At the federal level, the impeachment process is typically a three-step procedure. The first phase is typically an impeachment inquiry, though this is not a required stage. The two stages constitutionally required for removal are impeachment by the House of Representatives and trial by the United States Senate.

• First, the House investigates through an impeachment inquiry.
• Second, the House of Representatives must pass, by a simple majority of those present and voting, articles of impeachment, which constitute the formal allegation or allegations. Upon passage, the defendant has been "impeached".
• Third, the Senate tries the accused. In the case of the impeachment of a president, the chief justice of the United States presides over the proceedings. For the impeachment of any other official, the Constitution is silent on who shall preside, suggesting that this role falls to the Senate's usual presiding officer, the president of the Senate, who is also the vice president of the United States. Conviction in the Senate requires the concurrence of a two-thirds supermajority of those present. The result of conviction is removal from office and (optionally, in a separate vote) disqualification from holding any federal office in the future, which requires a concurrence of only a majority of senators present.

Impeachment in the House of Representatives

Impeachment proceedings may be requested by a member of the House of Representatives, either by presenting a list of the charges under oath or by asking for referral to the appropriate committee. The impeachment process may be requested 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. An impeachment proceeding formally begins with a resolution adopted by the full House of Representatives.

An impeachment resolution may first pass through a House committee before the full House votes on it. 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 (this vote is not law and is not required, US Constitution and US law).
