Article II defines the presidency and some executive powers

The executive Power is vested in a President who serves a four-year term.

Article II names the President 'Commander in Chief' and grants treaty and appointment powers, but Senate consent is required for treaties and many appointments.

The presidential veto procedure and the requirement for congressional consideration of vetoes are set out in Article I, Section 7, not in Article II.

Article II Section 4 provides that the President, Vice President, and other civil officers 'shall be removed from Office on Impeachment and Conviction', while the impeachment power is exercised by the House and the trial by the Senate.

Presidential succession and incapacity rely on the 25th Amendment (ratified 1967) and the Presidential Succession Act; Article II contains earlier, limited succession language.
