The President of the United States is considered one of the world’s most powerful people. The role includes being Commander-in-chief of the world’s most expensive military with the largest nuclear arsenal and leading the nation having the largest economy by real and nominal GDP, described as the world’s only contemporary superpower. The office of the president holds significant hard and soft power both in the United States and abroad.

Article II of the U.S. Constitution vests the executive power of the United States in the president. The power includes execution of federal law, alongside the responsibility of appointing federal executive, diplomatic, regulatory and judicial officers, and concluding treaties with foreign powers with the advice and consent of the Senate. The president is further empowered to grant federal pardons and reprieves, and to convene and adjourn either or both houses of Congress under extraordinary circumstances. The president is largely responsible for dictating the legislative agenda of the party to which the president is enrolled. The president also directs the foreign and domestic policy of the United States. Since the founding of the United States, the power of the president and the federal government has grown substantially.
