The situations of presidential incapacity (e.g. for medical reasons), and of presidential suspension due to the acceptance of impeachment charges, differ from the case of presidential travel abroad because, while the absence of the president from the country triggers the assumption of the powers of the office by an acting president, in that specific case, powers are not transferred from the president to the acting president, and instead two centers of authority remain in place personifying the presidency. In the cases of presidential incapacity or of suspension due to impeachment, however, the president is relieved of the powers of the office, and the duties of the presidency are therefore totally transferred to the acting president for the duration of his service.
