What is impeachment
Last updated: April 1, 2026
Key Facts
- In the U.S., the House of Representatives brings impeachment charges while the Senate holds a trial and votes on removal, requiring a two-thirds majority
- Impeachment addresses 'high crimes and misdemeanors' but these terms are defined by Congress rather than fixed legal standards
- Only two U.S. Presidents have been impeached: Andrew Johnson (1868) and Bill Clinton (1998), though neither was convicted and removed
- Impeachment is fundamentally a political process, not a criminal one, designed as a constitutional safeguard against abuse of power
- Many countries have similar mechanisms: the U.K. has parliamentary votes of no confidence, Germany has constructive votes of no confidence, and other democracies have comparable processes
Definition and Purpose
Impeachment is a formal process by which a legislative body charges a government official with misconduct or crimes committed while in office. Contrary to common misconception, impeachment itself does not remove an official from office—it is merely the formal charge or indictment. Removal requires a subsequent trial and vote, typically with a supermajority threshold. Impeachment functions as a constitutional check on executive power, allowing legislators to hold officials accountable for abuse of authority.
The U.S. Impeachment Process
The United States Constitution outlines impeachment procedures in Article II. The House of Representatives has the sole power to impeach, meaning it brings charges by majority vote. The Senate then conducts a trial where the accused official may defend themselves. Conviction and removal require a two-thirds majority in the Senate. The Chief Justice presides over presidential impeachment trials. This two-chamber structure ensures that impeachment cannot be weaponized by a simple majority but requires substantial consensus for removal.
Grounds for Impeachment
The Constitution specifies that impeachment addresses 'high crimes and misdemeanors,' deliberately broad language. These terms are not legally defined in criminal code but rather determined by Congress through political judgment. This grants Congress flexibility to address various forms of misconduct, including abuse of power, obstruction of Congress, and violation of the public trust—matters that might not constitute traditional crimes.
Historical Examples
President Andrew Johnson was impeached in 1868 for allegedly violating the Tenure of Office Act but acquitted in the Senate by one vote. President Bill Clinton was impeached in 1998 for perjury and obstruction of justice regarding testimony about his personal conduct, but the Senate fell short of the two-thirds majority needed for conviction. Neither president was removed, demonstrating the high bar for conviction.
Global Impeachment Processes
Parliamentary democracies worldwide employ similar mechanisms for accountability. The United Kingdom uses votes of no confidence, Germany employs constructive votes of no confidence, Brazil, South Korea, and other nations have impeachment procedures. These mechanisms reflect the universal democratic principle that elected officials remain accountable to legislative bodies representing the people.
Related Questions
What is the difference between impeachment and removal?
Impeachment is the formal charge brought by the House of Representatives, while removal is the actual dismissal from office voted on by the Senate. Impeachment charges do not guarantee removal; conviction requires a separate supermajority vote.
Can a president be impeached for anything?
Technically, Congress determines what constitutes 'high crimes and misdemeanors,' so the grounds are flexible. However, impeachment requires political will and typically addresses serious abuses of power, not minor or personal matters.
What happens if a president is impeached but not removed?
If impeached but not convicted, the president remains in office and continues their term. The impeachment becomes a historical record of the charges brought, but carries no legal consequences for removal or criminal punishment.
