Nancy Pelosi and impeachment are closely linked in public memory because she was Speaker of the House in 2019 when the House first voted to impeach a U.S. president in the 21st century, and she navigated the subsequent Senate trial in 2020. This is an evergreen explainer that clarifies what impeachment means, distinguishes it from removal, reviews the two presidential impeachments that occurred while Pelosi served as Speaker, and outlines the constitutional role of the Speaker in initiating and managing impeachment proceedings.
What Impeachment Is and How It Works
Impeachment in the United States is a constitutional process, not a criminal charge, that begins in the House of Representatives and can result in removal from office only after a conviction in the Senate. It is designed to hold federal officials accountable for serious misconduct. The House alone holds the power to impeach by majority vote; the Senate then conducts a trial that can lead to removal from office, and optionally bar the person from future federal office. The Speaker of the House, as the presiding officer of the chamber, plays a central role in deciding whether to refer alleged offenses to the Judiciary Committee and, in some instances, in managing House debate and negotiations.
Key Procedures and Constitutional Powers
Initiation and Referral in the House
The Constitution gives the House the sole power to impeach. In practice, resolutions to impeach are typically referred to the House Judiciary Committee, though the full House can, by simple majority, adopt rules or a resolution to proceed. The Speaker can decline to bring a resolution to the floor or can support moving it to committee and then to a full vote. The Senate has the sole power to try all impeachments, with the Chief Justice presiding when the president is tried. A two-thirds vote in the Senate is required to convict and remove from office; a simple majority is required to impeach in the House.
Impeachment Compared to Other Measures
- Impeachment is not removal; it is only the accusation stage that triggers a Senate trial.
- Removal from office requires a Senate conviction, not a House vote alone.
- Expulsion applies only to members of Congress and requires a two-thirds vote of that chamber.
- Censure is a formal rebuke that does not remove office and applies only to members of Congress.
Impeachment of President Donald Trump During Pelosi’s Speakership
During Nancy Pelosi’s tenure as Speaker, the House impeached President Donald Trump twice. The first impeachment occurred in December 2019 on articles of abuse of power and obstruction of Congress related to Ukraine, and the House approved both articles largely along party lines. The Senate trial in early 2020 ended in acquittal on both articles, failing to reach the two-thirds majority needed for removal. The second impeachment took place in January 2021 following the events at the U.S. Capitol on January 6. The House approved a single article of incitement of insurrection, and the Senate trial, which began after Trump had left office, ended in a vote that fell short of the two-thirds threshold for removal.
Notable Details
Pelosi’s decisions shaped the timeline and strategy of both impeachments, including the timing of referrals to the Judiciary Committee and the management of negotiations around the articles and the subsequent Senate trials. Public statements, negotiations with party members, and communications with the Senate influenced how each impeachment process unfolded. The House also adopted other resolutions censuring the president and holding administration witnesses in contempt, which complemented the impeachment process but did not result in removal.

Conclusion
Nancy Pelosi’s involvement in impeachment is defined by her constitutional role as Speaker during two presidential impeachments initiated by the House and tried by the Senate. Impeachment itself is a House power to accuse, not a removal mechanism, and removal requires a Senate conviction. Understanding these distinctions and Pelosi’s procedural decisions clarifies her influence on the timeline and outcomes of those high-profile proceedings.
