The President of the United States is the head of the executive branch of the government. The main duty of the executive branch is to make sure the laws passed by Congress are put into effect. Article I, section 7 and Article II, Sections 2 and 3 of The Constitution of the United States specifically express the powers of the President so that he may fulfill his duty as President.

Command the Military

The President is the Commander in Chief of the United States Armed Forces. When men and women enlist in the military, they must take an oath to obey the orders of the President, the highest ranking officer of the military. The President can deploy troops overseas, but he must get the approval of Congress to declare war.

Grant Reprieves and Pardons

Except in the case of impeachment, the President has the power to grant reprieves and pardons for federal crimes. A reprieve temporarily postpones punishment for a crime. A pardon forgives the crime and the penalty for the crime. Reprieves and pardons do not need the approval of Congress.

Make Treaties

The Constitution grants the President the power to make treaties, or formal agreements, with other nations. He must receive consent from two-thirds of the Senate to make the treaty official.

Appoint Ambassadors and Officers

The President's appointments include public ministers and consuls, Supreme Court justices, cabinet members, U.S. attorneys, and all officers whose appointments are not otherwise provided for in the Constitution. Some of those appointed to positions by the President must also receive Senate confirmation.

Grant Commissions and Call Special Sessions of Congress

The President has the power to fill vacancies that may happen during Senate recess. These commissions expire at the end of the next Senate session. On extraordinary occasions, the President may convene and adjourn both houses of Congress, or either of them, as he thinks proper.

Approve or Veto Bills

The Constitution grants the President the power to approve bills of legislation submitted by Congress into law. If he objects to the bill, the Constitution states that he may veto the bill and send it back to Congress.
