What Impeachment Means and How Removal Works
Impeachment is a formal accusation by the House of Representatives that a federal official, including the president, has committed conduct serious enough to warrant removal from office. It does not, by itself, remove anyone from power. After impeachment, the Senate holds a trial. If two thirds of senators present vote to convict, the official is removed from office and may be disqualified from holding future federal office. Because removal requires a Senate conviction, a president can be impeached by the House but not removed if the Senate does not reach a two thirds majority to convict.
Historical Overview of U.S. Presidential Impeachments
Only three U.S. presidents have been impeached: Andrew Johnson in 1868, Bill Clinton in 1998, and Donald Trump in 2019 and again in 2021. None of those impeachments resulted in removal from office, as none secured a two thirds Senate conviction. The House did not bring impeachment charges against several other presidents, and no president has ever been both impeached and removed. These historical cases illustrate the political and constitutional thresholds involved, where party control of the Senate and the high bar for conviction shape outcomes more than the initiation of impeachment itself.
Andrew Johnson (1868)
Andrew Johnson was impeached by the House in 1868, primarily over his handling of Reconstruction and violations of the Tenure of Office Act. The Senate trial fell one vote short of the two thirds majority needed to convict and remove him from office.
Bill Clinton (1998–1999)
Bill Clinton was impeached by the House in 1998 on charges of perjury and obstruction of justice related to the Monica Lewinsky scandal. The Senate trial in early 1999 did not reach the threshold for conviction and removal.
Donald Trump (2019 and 2021)
Donald Trump was impeached twice: first in 2019 for abuse of power and obstruction of Congress, and again in 2021 for incitement of insurrection after the attack on the U.S. Capitol. Both impeachment resolutions passed the House, but his Senate trials did not produce convictions that led to removal.
How Impeachment Compares to Other Checks on Presidential Power
Impeachment is one constitutional mechanism for accountability, distinct from censure, primary challenges, elections, and criminal prosecution. Censure is a formal congressional rebuke that does not remove a president or strip powers. While a president may face criminal investigation and indictment after leaving office, impeachment is a political process conducted by Congress rather than a criminal proceeding. These different tools address separate questions of legality, political legitimacy, and fitness for office.

Practical Implications of Impeachment for the Presidency
The rarity of removal through impeachment underscores the high bar set by the Constitution. For a removal to occur, the House must approve articles of impeachment by a simple majority, and the Senate must then convict by a two thirds majority of senators present. In practice, this usually requires significant bipartisan support or overwhelming evidence and public consensus. The process is intentionally difficult because removal displaces an elected leader and has major democratic consequences. As a result, impeachment is often used as a tool of political accountability and leverage as much as a successful mechanism for ousting a president.
Common Misunderstandings and Clarifications
- Being impeached does not mean a president is removed from office; it means the House has formally accused them and the matter moves to Senate trial.
- No U.S. president has been removed from office through impeachment and conviction.
- Impeachment is a political process in the legislature, not a criminal prosecution, and it does not prevent later criminal charges.
- A president who is removed can be disqualified from holding future federal office if the Senate votes for that penalty, but such a penalty requires a separate vote after conviction.
- Presidents can leave office for other reasons, such as resignation, death, or the end of their term, without ever being impeached.
Context and Takeaways
As a verified explanation, this overview clarifies that impeachment is an accusation and that removal requires a Senate conviction. Across U.S. history, three presidents have been impeached, but none have been removed from office by this process. Understanding the distinction between impeachment and removal, the required thresholds, and the political nature of the process helps explain why outcomes vary and why impeachment remains a rare but significant constitutional tool.
Looking Ahead
Future impeachment efforts would follow the same constitutional design: House accusation followed by a Senate trial. The outcomes continue to depend on evidentiary clarity, legal arguments, and political dynamics in the Senate. Because no president has yet been removed through impeachment, this process remains an important hypothetical check rather than a common historical event.
FAQ
Reader questions
Can a president be impeached and removed for anything?
Impeachable offenses are generally understood to include treason, bribery, or other high crimes and misdemeanors. The exact scope has been debated, but it is not limited to criminal violations defined in ordinary statutes.
What happens if a president is convicted by the Senate?
The president is removed from office immediately. The Senate may also vote to disqualify the individual from holding future federal office, though that is a separate vote and requires a simple majority.
Has any president resigned to avoid impeachment?
Richard Nixon resigned in 1974 while facing near-certain impeachment and removal, but no sitting president has been both impeached and removed from office.
Can a former president be impeached and removed?
The Senate can try a former official for offenses committed while in office. If convicted, the Senate may disqualify them from future office, but removal from office is not possible because the person is no longer serving.
How does impeachment differ from the Twenty-Fifth Amendment?
The Twenty-Fifth Amendment addresses presidential inability to discharge duties, typically for medical reasons, and involves the vice president and cabinet. Impeachment addresses alleged misconduct and is a legislative, not medical, process.
Do impeachment and removal prevent later criminal prosecution?
No. Impeachment and removal are political processes. A president who leaves office can later be subject to criminal investigation and prosecution for the same conduct, as happened with several officials who faced legal consequences after leaving federal office.
