How Impeachment Works: The Constitutional Process Most Americans Get Wrong

Here is how impeachment works in one paragraph. The House of Representatives impeaches by simple majority — that is an indictment, not a removal. The Senate then holds a trial and needs a two-thirds supermajority to convict and remove. That gap between a simple majority and 67 votes is the entire story: it is why three presidents have been impeached, and why none of them has ever been removed from office.

Most of the confusion around impeachment comes from a single word doing two jobs. In everyday speech, “impeached” sounds like “fired.” In the Constitution, it means “charged.” Everything downstream — the drama, the disappointment, the accusations of a rigged process — flows from that mismatch.

What does the Constitution actually say about impeachment?

Less than you would expect — the mechanism is spread across three short passages.

Article I gives the House “the sole Power of Impeachment.” It gives the Senate “the sole Power to try all Impeachments,” requires two-thirds of the members present to convict, and specifies that the Chief Justice presides when a president is tried — not the vice president, who would be next in line.

Article II names the offenses: “Treason, Bribery, or other high Crimes and Misdemeanors.” And it limits the penalty. Conviction can do exactly two things: remove the official and disqualify them from future federal office. No fines. No prison — though a convicted official remains liable to ordinary criminal prosecution afterward, in a regular court, like anyone else. One detail that matters enormously in a crisis: the pardon power comes with an express carve-out, “except in Cases of Impeachment.” No president can pardon their way out of this one.

How impeachment works, step by step: what happens after the House votes?

The sequence is more procedural than cinematic, which is precisely why it gets misunderstood.

1. Investigation. The House opens an inquiry, usually through the Judiciary Committee. Subpoenas issue, witnesses testify, and nothing is binding yet.
2. Articles of impeachment. The committee drafts specific charges. Each article is a separate accusation, voted separately.
3. The House floor vote. A simple majority on any single article impeaches the official. One article is enough. This is the moment headlines call “impeachment” — and the official remains in office with every power of the job intact.
4. House managers. The House appoints members to serve as prosecutors in the Senate trial.
5. The Senate trial. Senators sit as jurors under oath. The managers prosecute; the official defends. The Senate writes its own rules for each trial — witnesses, length, evidence — which is why no two trials look alike.
6. The verdict. Two-thirds of senators present must vote to convict on at least one article. In a full chamber, that is 67 of 100. Anything less is acquittal.
7. Disqualification. Only after conviction, by a separate simple-majority vote, can the Senate bar the person from future federal office.

What counts as a “high crime and misdemeanor”?

This is the load-bearing ambiguity of the whole system. The phrase is never defined — not in the Constitution, not in statute.

Gerald Ford, then House minority leader, gave the most quoted answer in 1970: an impeachable offense is “whatever a majority of the House of Representatives considers it to be at a given moment in history.” Cynical, but not wrong as a description of practice.

The scholarly answer is narrower. The framers borrowed the phrase from British parliamentary practice, where it described serious abuses of public trust — corruption, betrayal, gross dereliction of duty. That cuts both ways. An impeachable offense need not be a statutory crime; abusing an office in ways no criminal code anticipated can qualify. And not every crime is impeachable; a president who shoplifts has committed a crime that has nothing to do with the powers of the presidency.

The vagueness is deliberate. The framers could not enumerate every way a republic might be betrayed, so they wrote a standard instead of a list. The cost is that the standard floats — it means, in practice, whatever the political moment says it means.

Why has no president ever been removed from office?

Three presidents have been impeached: Andrew Johnson in 1868, Bill Clinton in 1998, and Donald Trump twice, in 2019 and 2021. All four trials ended in acquittal. Johnson came closest — the Senate fell a single vote short. Richard Nixon is the asterisk: the Judiciary Committee approved articles in 1974, and he resigned before the full House could vote.

The reason is arithmetic, not conspiracy. Sixty-seven votes cannot be assembled from one faction. Conviction requires a substantial number of senators to vote against the party holding the White House — in public, on the record, with a primary electorate watching. The framers set the bar that high on purpose, in an era before organized national parties existed. They were guarding against removal over ordinary policy disagreement. They did not anticipate party discipline pushing the threshold nearly out of reach in the other direction.

The process is not purely theoretical, though. Impeachment applies to all “civil Officers of the United States,” and the Senate has convicted and removed eight federal judges. The machinery works. It simply meets a different politics when the defendant is a president.

What does impeachment look like from a thriller writer’s desk?

I spent twenty years inside politics before I started writing fiction about it, and impeachment is a subject where reality outstrips anything I would dare invent. A body that is simultaneously prosecutor and jury. A trial whose only rules of evidence are the ones the jurors vote to give themselves. A defendant who keeps command of the armed forces throughout.

That is why the Bull Moose series keeps returning to constitutional pressure points rather than gunfights. The most frightening scenarios in American government are not the illegal ones — they are the technically permissible ones nobody expected anyone to attempt. The Nine-Hour President lives in exactly that space: a legitimate process, followed to the letter, producing an outcome the country never consented to.

If you want the shortest way in, start with The Senate Deception — it takes place in the chamber where all of this would ultimately be decided.

Frequently asked questions

Does being impeached mean a president is removed from office? No. Impeachment is the House’s charge, decided by simple majority. Removal requires a separate Senate trial and a two-thirds vote to convict. A president who is impeached but not convicted stays in office with all powers intact.

How many votes are needed to remove a president? Two-thirds of senators present — 67 votes in a full 100-member Senate — on at least one article of impeachment. Disqualification from future office is a separate vote requiring only a simple majority, and can happen only after conviction.

Can a president pardon their way out of impeachment? No. Article II grants the pardon power “except in Cases of Impeachment.” The pardon power reaches federal criminal prosecution, not the impeachment process itself.

Has any federal official ever actually been removed by impeachment? Yes — eight federal judges have been convicted by the Senate and removed from the bench. No president has been. The constitutional mechanism functions; the political math is simply different when the office in question is the presidency.
