To impeach a government official means to charge them with misconduct or wrongdoing while in office, often initiated by a legislative body. In the U.S., the House of Representatives has the authority to impeach federal officials, including the president, while the Senate conducts the trial to determine guilt or innocence. Impeachment serves as a critical mechanism for maintaining checks and balances within government, enabling accountability for any abuse of power, corruption, or other serious offenses. It underscores the importance of upholding ethical standards in public office.
