The Senate has an important check on the executive power by confirming Cabinet officials, judges, and other high officers "by and with the Advice and Consent of the Senate". It confirms most presidential nominees, but rejections are not uncommon. Furthermore, treaties negotiated by the President must be ratified by a two-thirds majority vote in the Senate to take effect. As a result, presidential arm-twisting of senators can happen before a key vote; for example, President Obama's secretary of state, Hillary Clinton, urged her former senate colleagues to approve a nuclear arms treaty with Russia in 2010. The House of Representatives has no formal role in either the ratification of treaties or the appointment of federal officials, other than in filling a vacancy in the office of the vice president; in such a case, a majority vote in each House is required to confirm a president's nomination of a vice president.
