Answer:
Impeachment in the United States is the process by which a legislature (usually in the form of the lower house) brings charges against a civil officer of government for crimes alleged to have been committed, analogous to the bringing of an indictment by a grand jury. Impeachment may occur at the federal level or the state level. The federal House of Representatives can impeach federal officials, including the president, and each state's legislature can impeach state officials, including the governor, in accordance with their respective federal or state constitution.
