Impeachment is the process whereby an elected official, such as a governor, is charged with, and tried for, crimes or misconduct committed in the course of office. Consequences resulting from conviction are generally limited to removal from office and prohibition against holding office in the future.

In most states, the process is similar to that used for impeachments of presidents at the federal level. If the lower chamber of a state legislature votes in favor of impeachment (i.e., votes to formally charge the governor with an impeachable offense), then the upper chamber functions as a court of impeachment and votes on whether to convict the governor. Oregon was the final state to provide gubernatorial impeachment powers to the state legislature when its voters passedMeasure 115 in November 2024.

There are some exceptions. InAlaska, the upper chamber votes to impeach and the lower chamber functions as the court of impeachment. InMissouri, impeachments are tried by a panel of seven judges selected by theMissouri State Senate, with a vote from five of the seven judges required to convict. InNebraska, if theunicameral legislature votes in favor of impeachment, the governor is tried by theNebraska Supreme Court. Finally, inOklahoma, an impeached governor is tried before both chambers of thestate legislature sitting in joint session.^[1]

Historic impeachments of governors

In the history of the United States, there are sixteen cases of a vote being carried out to impeach a governor. Of those, nine led to the impeached governor's removal from office. The National Conference of State Legislatures has suggested two potential reasons for the relative infrequency of gubernatorial impeachments: the perception that impeachment is a drastic measure and the likelihood of officers resigning before they can be impeached.^[3]
