In presidential systems, the upper house is frequently given other powers to compensate for its restrictions: Executive appointments, to the cabinet and other offices, usually require its approval’ and it frequently has the sole authority to give consent to or denounce foreign treaties. It has (in presidential systems) the sole power to try impeachments against the executive, following enabling resolutions passed by the lower house. In USA, the House of Congress and Senate are equal partners in the legislative process; however, the Constitution grants each chamber some unique powers. The Senate ratifies treaties and approves presidential appointments while the House initiates revenue-raising bills. The House initiates impeachment cases, while the Senate decides impeachment cases. A two-thirds vote of the Senate is required before an impeached person can be forcibly removed from office.
