The 25th Amendment explicitly states that if the president dies, resigns or is removed from office, the vice president becomes president, and also establishes a procedure for filling a vacancy in the office of the vice president. The Amendment further provides that the president, or the vice president and Cabinet, can declare the president unable to discharge his or her duties, in which case the vice president becomes Acting president. If the declaration is done by the vice president and Cabinet, the Amendment permits the president to take control back, unless the vice president and Cabinet challenge the president and two-thirds of both Houses vote to sustain the findings of the vice president and Cabinet. If the declaration is done by the president, he or she may take control back without risk of being overridden by the Congress.
