Impeachment is a rare and contentious process enshrined in the U.S. Constitution, providing a mechanism for removing a sitting President from office for wrongdoing and malfeasance while in office. The House of Representatives begins the process by investigating the President's conduct either through a whistleblower complaint, allegations of criminal activity, or a violation of the President's oath of office, leading to a recommendation of articles of impeachment and a full House vote. If the House votes in favor, the case is sent to the Senate for a trial, requiring a two-thirds majority to convict and remove the President from office. Impeachment ensures accountability, checking on the power of the executive branch, and safeguards against corruption and abuse of power.
