What Does It Mean to Impeach a President
Impeachment is a formal process by which a legislature charges a president with misconduct. In the United States, the House of Representatives has the sole power to impeach, while the Senate conducts the trial and decides removal. The Constitution defines impeachment as a check on executive power, not a criminal conviction. The process begins with an investigation, followed by a House vote on articles of impeachment, and, if approved, a Senate trial that can result in removal with a two-thirds majority. The latest public data on impeachment attempts and outcomes is available on the official U.S. House of Representatives website house.gov.
Impeachment is often confused with removal from office, but they are separate steps. A president can be impeached by the House and still remain in office if the Senate does not vote to convict. The grounds for impeachment are limited to treason, bribery, or other high crimes and misdemeanors as outlined in the Constitution. Public records show that several presidents have faced impeachment votes, while only a few have been removed after Senate trials.

How the Impeachment Process Works
House Investigation and Vote
The House Judiciary Committee typically leads the investigation, gathers evidence, and drafts articles of impeachment. After hearings, the full House votes on each article, and a simple majority is required to impeach. The latest public data shows that the House has voted on impeachment multiple times in U.S. history, with outcomes ranging from acquittal in the Senate to removal from office. Detailed timelines and vote counts are published by the Congressional Research Service crsreports.congress.gov.
Senate Trial and Removal
If the House impeaches, the case moves to the Senate, where senators act as jurors and the Chief Justice of the Supreme Court presides over presidential trials. A two-thirds supermajority of senators present is required to convict and remove the president. Historical data shows that several impeached presidents were acquitted by the Senate and remained in office. The Senate's official website provides current rules, schedules, and records of past impeachment trials senate.gov.
Historical Impeachment Outcomes and Data
Public records show that three U.S. presidents have been impeached by the House: Andrew Johnson, Bill Clinton, and Donald Trump. None of those presidents were removed by the Senate, as the required two-thirds majority was not reached. The latest available data includes detailed vote counts, articles of impeachment, and trial transcripts from the Congressional Record congress.gov.
Impeachment outcomes affect political markets, policy momentum, and public trust in institutions. Financial data firms track market reactions around impeachment votes and trials, showing short-term volatility but no consistent long-term trend tied directly to impeachment. For investors, understanding the constitutional process and historical data helps separate political events from economic fundamentals.
