Is the procedure by which “the President, Vice President, and all other civil officers of the United States,” including members of the federal judiciary, can be removed from office if guilty of “treason, bribery, or other high crimes and misdemeanors.” Articles of impeachment, or accusations of misconduct, are drafted in the House of Representatives and approved by majority vote; the trial is before the Senate, with a two?thirds vote needed for conviction. In cases of presidential impeachment, the trial is presided over by the chief justice. Conviction in a case of impeachment can result only in removal from office and disqualification from holding office in future, but does not prevent the guilty party from being held further accountable in regular courts of law. Finally, the presidential pardoning power does not extend to individuals convicted in cases of impeachment.
Encyclopedia Britannica
In common law, a criminal proceeding instituted against a public official by a legislative body. In Great Britain the House of Commons serves as prosecutor and the House of Lords as judge in an impeachment proceeding. In the federal government of the United States the House of Representatives institutes the impeachment proceedings, and the Senate acts as judge. In Great Britain conviction on an impeachment has resulted in fine and imprisonment, and even in execution, whereas in the United States the penalties extend no further than removal and disqualification from office.

Impeachment is a fundamental constitutional power belonging to Congress. This safeguard against corruption can be initiated against federal officeholders from the lowest cabinet member, all the way up to the president and the chief justice of the U.S. Supreme Court. Besides providing the authority for impeachment, the U.S. Constitution details the methods to be used. The two-stage process begins in the House of Representatives with a public inquiry into allegations. It culminates, if necessary, with a trial in the Senate. State constitutions model impeachment processes for state officials on this approach. At both the federal and state levels, impeachment is rare: From the passage of the Constitution to the mid-1990s, only 50 impeachment proceedings were initiated, and only a third of these went as far as a trial in the Senate. The reluctance of lawmakers to use this power is a measure of its gravity; it is generally only invoked by evidence of criminality or substantial abuse of power.
The roots of impeachment date to ancient Athens. Its place in the U.S. Constitution was secured by the influence of English Common Law on the Framers of the Constitution. Originally, any English subject, politician, or ruler could institute impeachment charges in Parliament. By the fourteenth century, this power became the exclusive domain of the House of Commons and the House of Lords. In 1776, the American colonies included much of the English tradition in state constitutions, but the delegates of the Constitutional Convention hotly debated how best to embody it in the federal Constitution. Their most contentious question was over the offenses that should be considered impeachable.

Impeachment is a formal process in which an elected official is accused of unlawful activity, and which may or may not lead to the removal of that official from office. It is the first of two stages. Impeachment does not necessarily result in removal from office; it is only a legal statement of charges, parallel to an indictment in criminal law. An official who is impeached faces a second legislative vote (whether by the same body or another), which determines conviction, or failure to convict, on the charges embodied by the impeachment. Most constitutions require a supermajority to convict. Although the subject of the charge is criminal action, it does not constitute a criminal trial; the only question under consideration is the removal of the individual from office, and the possibility of a subsequent vote preventing the removed official from ever again holding political office in the jurisdiction where he was removed.
