Federal government of the United States
Executive branch
The president may sign legislation passed by Congress into law or may veto it, preventing it from becoming law unless two-thirds of both houses of Congress vote to override the veto. The president may unilaterally sign treaties with foreign nations. However, ratification of international treaties requires a two-thirds majority vote in the Senate. The president may be impeached by a majority in the House and removed from office by a two-thirds majority in the Senate for "treason, bribery, or other high crimes and misdemeanors". The president may not dissolve Congress or call special elections but does have the power to pardon or release criminals convicted of offenses against the federal government (except in cases of impeachment), enact executive orders, and (with the consent of the Senate) appoint Supreme Court justices and federal judges.
