The Constitution explicitly assigns the president the power to sign or veto legislation, command the armed forces, ask for the written opinion of their Cabinet, convene or adjourn Congress, grant reprieves and pardons, and receive ambassadors.
A governor's official duties can include signing bills into law, serving as commander-in-chief of the state's National Guard and militia forces, convening special sessions of the state legislature, delivering a "state of the state" address to citizens, granting commutations and pardons to prisoners
