Impeachment proceedings against the President in the United States can be initiated by the House of Representatives. The process begins with allegations of misconduct, which can include crimes, abuses of power, or breaches of public trust. Upon a majority vote, the House can bring formal charges, known as articles of impeachment. Following this, the case is sent to the Senate for trial, where a two-thirds majority is required for conviction and removal from office. Impeachment serves as a crucial mechanism for holding the President accountable and ensuring the integrity of the executive branch.
