Presidential powers refer to the authority granted to the President of a country, often defined by the constitution. In the United States, these powers include the ability to sign or veto legislation, command the military, and appoint federal judges. The President also has the power to issue executive orders, which direct the operations of the federal government. Additionally, the President plays a key role in foreign policy, representing the nation in diplomatic matters and negotiating treaties, which must be ratified by the Senate. These powers are balanced by the legislative and judicial branches to prevent any one branch from becoming too powerful.
