who is the designated survivor of the united states
Designated survivor Only Cabinet members who are eligible to succeed to the presidency (i.e., natural-born citizens over the age of 35, who have resided in the United States for at least 14 years) can be chosen as designated survivors. The designated survivor is provided presidential-level security and transport for the duration of the event. An aide carries a nuclear football with them. However, they are not given a briefing on what to do in the event that the other successors to the presidency are killed.[2]
