The person is chosen to stay at an undisclosed secure location, away from such events such as State of the Union addresses and presidential inaugurations.
Being the designated survivor does not guarantee that this official will be the person to assume the presidency in such a situation.
For the 2010 State of the Union address, Shaun Donovan, the secretary of housing and urban development, was the designated survivor, but Secretary of State Hillary Clinton also was absent from the address, for a conference in London; had a calamity occurred, Clinton, not Donovan, would have become acting president, because her office was higher in the line of succession.
[2] In a 2016 interview, Jon Favreau, a speechwriter for President Barack Obama, said that the procedure for picking a designated survivor for a State of the Union address was "entirely random", but later clarified that the content of the speech played a role in who was permitted to be absent.
Favreau said that for a State of the Union address in which Obama's education policy was a major focus, for example, the secretary of education, Arne Duncan, was not chosen as the designated survivor, because it was thought that he should attend and represent his department.
