What are the 4 main powers of the president?

The expressed powers of the President of the United States are set down in Article II of the Constitution. The major function of the executive branch is to enforce the laws.The powers are of two sorts: those exercised alone without legislative approval and those that require consent of the Senate or House. Powers of the President Alone: commander in chief of the armed forces; commission officers of the armed forces; grant reprieves and pardons for federal offenses (except impeachment); convene Congress into special session; receive ambassadors; take care that the laws be faithfully executed; make use of the "executive power" of the office, such as the veto power; give an annual State of the Union Address to Congress; appoint officials to lesser offices. Powers shared with the Senate/House: make treaties; appoint ambassadors, judges, and high governmental officials; approve legislation. The President also has “implied powers.” These are powers that are not listed in the Constitution but have been used by presidents as conditions change.
