It is the "political death penalty." That is how many constitutional scholars describe the process of removing a sitting leader. But when you actually sit down to look at what are grounds to impeach a president, the text is surprisingly sparse. It feels like the Founders left us a riddle. They wrote fewer than twenty words to define the most explosive power in the American government.
Most people think it’s about a specific crime. You broke the law, you go to jail, right? Not exactly. Impeachment isn't a criminal trial. It’s a constitutional safety valve. If you’re looking for a clear-cut list of "don'ts" in the back of the manual, you’re going to be disappointed. It’s way more complicated—and way more interesting—than a simple legal checklist.
The Big Three: Treason, Bribery, and the Mysterious "Other"
Article II, Section 4 of the U.S. Constitution is where the magic happens. It says a President can be removed for "Treason, Bribery, or other high Crimes and Misdemeanors." Treason is easy. It’s defined elsewhere in the Constitution as levying war against the U.S. or giving aid and comfort to enemies. Bribery is also pretty straightforward; it’s the "pay to play" stuff everyone hates.
But then we hit the wall: "high Crimes and Misdemeanors."
What on earth does that mean? Honestly, it depends on who you ask and what year it is. In 1970, Gerald Ford—who wasn't even President yet—famously said that an impeachable offense is "whatever a majority of the House of Representatives considers it to be at a given moment in history." That sounds cynical. It's also basically true.
The word "high" in that phrase doesn't mean "very serious" in the way we use it today. In the 18th century, it referred to crimes committed by people in high office. It’s about a breach of the public trust. You don't necessarily need to violate a specific statute found in a thick law book to be impeached. You just have to fail at the job in a way that threatens the Republic.
It’s Not Just About Breaking the Law
Here is the thing that trips everyone up. A President can commit a crime and not be impeached. Conversely, a President can be impeached without technically breaking a single criminal law.

Imagine a President who just... stops working. They decide to move to a beach in Fiji, refuse to sign any bills, ignore every phone call from the Joint Chiefs, and spend four years drinking margaritas. Is that a crime? No. Is it a "high Misdemeanor"? Absolutely. It is a dereliction of duty.
Alexander Hamilton wrote in Federalist No. 65 that impeachment is for "the abuse or violation of some public trust." He called these "POLITICAL" offenses because they relate to the "injuries done immediately to the society itself."
This is why the process happens in Congress and not in a courtroom with a robe-clad judge and a jury of peers. The House acts as the grand jury, and the Senate acts as the trial court. It is a political process designed to handle a political crisis.
The Andrew Johnson Precedent
Take Andrew Johnson. He was the first President to be impeached, back in 1868. The "ground" for his impeachment was violating the Tenure of Office Act. He fired his Secretary of War, Edwin Stanton, without the Senate's permission. Was it a real crime? The Supreme Court later suggested the law itself was probably unconstitutional. But the House didn't care. They wanted him out because he was blocking Reconstruction after the Civil War. It was a power struggle wrapped in a legal argument.
The Modern Interpretation of Impeachable Acts
When we look at what are grounds to impeach a president in the modern era, the focus has shifted toward "Abuse of Power" and "Obstruction of Congress."
We saw this with Richard Nixon, though he resigned before the full House could vote. The articles drafted against him included things like using the IRS to harass political enemies and using the FBI to cover up the Watergate break-in. This wasn't just about a "third-rate burglary." It was about using the machinery of the state to keep himself in power.

Specific Examples of Potential Grounds:
- Abuse of Presidential Power: Using the office for personal or political gain rather than the national interest.
- Obstruction of Justice: Trying to kill investigations into your own conduct or the conduct of your associates.
- Corruption: This overlaps with bribery but can include things like violating the Emoluments Clause (taking money from foreign governments).
- Failure to Execute the Law: If a President flat-out refuses to enforce laws passed by Congress because they personally dislike them.
The Misconception of "Misdemeanors"
Let’s talk about that word "misdemeanor." In 2026, a misdemeanor is what you get for shoplifting or public intoxication. It's a minor thing. But back in 1787, the term had a much broader meaning. It meant "mis-demeanor"—bad behavior or misconduct.
If a President acts in a way that is totally incompatible with the office, that's a misdemeanor in the constitutional sense. The Founders were terrified of a "demagogue" or a "tyrant." They wanted a way to get rid of someone who was clearly unfit, even if they hadn't been caught with their hand in the literal cookie jar yet.
But there’s a flip side. Because the definition is so vague, there is a constant fear that impeachment will be used as a political weapon. If the House is controlled by Party A and the President is Party B, what’s stopping them from impeaching the President just because they don't like his tax policy?
In theory, the "high" threshold is supposed to prevent this. In practice, the only real check is the voters. If a party impeaches a President for flimsy reasons, they usually pay for it at the next election.
How the Process Actually Functions
It starts in the House Judiciary Committee. They investigate. They call witnesses. They argue about subpoenas. If they find enough evidence, they draft "Articles of Impeachment." Think of these as the formal charges.
If a simple majority of the House votes "yes" on any of those articles, the President is officially impeached. But—and this is a huge "but"—they aren't removed yet.

The whole thing then moves to the Senate. The Chief Justice of the Supreme Court comes over to preside. The Senators act as the jury. To actually kick the President out of the White House, you need a two-thirds majority in the Senate.
That is a incredibly high bar. It’s why, as of now, no U.S. President has ever been removed from office via impeachment. Nixon resigned, and Johnson, Clinton, and Trump were all acquitted by the Senate.
Navigating the Grey Areas
It's tempting to want a clear list.
- Did they lie under oath?
- Did they take money from a foreign spy?
- Did they use the military for a private errand?
If the answer is yes, then impeach. But the law doesn't work that way. Clinton was impeached for perjury and obstruction of justice related to a private affair. The House felt it met the criteria. The Senate felt it didn't rise to the level of removing a leader chosen by the people.
This tension is the whole point. The grounds for impeachment are intentionally flexible so they can adapt to threats the Founders couldn't imagine—like cyber warfare or digital election interference.
Actionable Insights for the Informed Citizen
Understanding the grounds for impeachment isn't just for law students. It’s for anyone who wants to cut through the noise of cable news.
- Read the Articles: Whenever a President is impeached, read the actual Articles of Impeachment. Don't rely on a summary. See exactly what they are being accused of and whether it relates to "public trust" or a personal grudge.
- Look for the "Nexus": Ask if there is a connection between the alleged act and the President's official duties. Usually, for an impeachment to be successful in the court of public opinion, there needs to be a clear link between the behavior and the misuse of the office.
- Differentiate Crime vs. Impeachment: Remind yourself that a "not guilty" verdict in a criminal court doesn't mean a President can't be impeached, and an acquittal in the Senate doesn't mean the President didn't do something wrong. They are two different systems with two different goals.
- Monitor the Precedent: Each impeachment trial sets a new "standard" for the future. Pay attention to the legal arguments made by both the "House Managers" (the prosecutors) and the President's defense team. These arguments become the blueprint for the next time it happens.
The reality of what are grounds to impeach a president is that it's a living, breathing part of the Constitution. It’s messy, it’s loud, and it’s deeply partisan. But it’s also the ultimate "break glass in case of emergency" tool that ensures no one, not even the person in the Oval Office, is truly above the law.
