The word “impeachment” often conjures up images of high-stakes courtroom drama and political upheaval. But beyond the headlines, how to impeach a president is a precisely defined constitutional process. It is the ultimate “emergency brake” in the American system of checks and balances, designed to hold the highest office in the land accountable.
In 2026, understanding this process is more relevant than ever. Impeachment isn’t just a single vote; it’s a multi-stage legal and political journey that moves from the halls of the House of Representatives to a formal trial in the Senate.
In this guide, we will break down the constitutional grounds, the procedural steps, and exactly what happens once a president is officially “impeached.”
Key Takeaways
- Impeachment is an Indictment: To be “impeached” means to be formally charged, not necessarily removed from office.
- The House Initiates: Only the House of Representatives has the power to bring impeachment charges.
- The Senate Tries: The Senate acts as the jury and holds the power to convict and remove.
- Constitutional Grounds: A president can be impeached for “Treason, Bribery, or other high Crimes and Misdemeanors.”
- Supermajority Required: While the House needs a simple majority, the Senate requires a two-thirds vote to convict.
1. The Legal Grounds: What is an Impeachable Offense?
The U.S. Constitution (Article II, Section 4) is quite specific about why a president can be removed. However, the definition of these terms has been debated for over two centuries.
- Treason and Bribery: These are legally defined crimes.
- High Crimes and Misdemeanors: This is a broader category. It doesn’t necessarily mean a literal “crime” like theft. Historically, it refers to an abuse of power or a violation of the public trust that makes an official unfit for office.

2. Phase One: The House of Representatives
The journey of how to impeach a president always begins in the lower house of Congress. Think of this stage like a grand jury investigation.
- Impeachment Inquiry: A committee (usually the Judiciary Committee) investigates allegations of wrongdoing. They gather evidence, call witnesses, and issue subpoenas.
- Articles of Impeachment: If the committee finds sufficient evidence, they draft “Articles of Impeachment”—specific charges against the president.
- The House Vote: The full House of Representatives debates and votes on the articles. A simple majority (50% + 1) is all that is required. If at least one article passes, the president is officially “impeached.”
The Impeachment Process: House vs. Senate
| Feature | House of Representatives | U.S. Senate |
| Primary Role | The Prosecutor (Brings charges) | The Jury (Holds the trial) |
| Action Taken | Votes on “Articles of Impeachment” | Votes to “Convict” or “Acquit” |
| Vote Required | Simple Majority | Two-Thirds Supermajority |
| Result of Vote | Formal Indictment | Removal from Office |
| Presiding Officer | Speaker of the House | Chief Justice of the Supreme Court |
3. Phase Two: The Senate Trial
Once the House impeaches, the action moves across the Capitol to the Senate. This is where the actual trial takes place to determine if the president should stay or go.
- The Managers: A group of House members (Managers) acts as the prosecution.
- The Defense: The president is represented by their own legal counsel.
- The Judge: In a presidential trial, the Chief Justice of the Supreme Court presides over the proceedings to ensure fairness.
- The Jury: All 100 Senators sit as jurors and must take an oath to be impartial.
4. The Final Verdict: Removal or Acquittal
After hearing arguments and reviewing evidence, the Senate meets to vote on each Article of Impeachment.
- Acquittal: If the vote falls short of the two-thirds threshold, the president is acquitted and remains in office. This has been the outcome for every presidential impeachment trial in U.S. history (Johnson, Clinton, and Trump).
- Conviction: If 67 out of 100 Senators vote to convict on any single article, the president is immediately removed from office.
- Disqualification: After a conviction, the Senate can hold a separate vote to permanently bar the individual from holding any federal office in the future.
Conclusion
Learning how to impeach a president reveals the deliberate difficulty the Founders built into the system. While the House can impeach with a simple majority to signal a serious breach of trust, the high bar of a two-thirds Senate vote ensures that removal from office is only possible with broad, bipartisan consensus.

FAQ Section
Q: Does impeachment mean the president is automatically fired?
A: No. Impeachment is only the first half of the process. It is equivalent to a criminal indictment. A president is only “fired” (removed) if the Senate subsequently votes to convict them.
Q: Who takes over if a president is removed?
A: Under the 25th Amendment and the Presidential Succession Act, the Vice President immediately takes the oath of office. If the Vice President is also unavailable, the Speaker of the House is next in line.
Q: Can a president pardon themselves from impeachment?
A: No. The Constitution explicitly states that the President’s power to grant pardons does not extend to “Cases of Impeachment.”
Q: Has a U.S. president ever been removed via impeachment?
A: No. Andrew Johnson, Bill Clinton, and Donald Trump (twice) were all impeached by the House but were acquitted by the Senate. Richard Nixon resigned before the House could vote on his impeachment.
