What about someone turning a light on or off in a room they are in. Does that cause a problem?
someone else is allowed to turn on and off lights, to wash the dishes, etc... Especially if they are not directly requesting them to do so.
(Ideal if this is not done in public, and also people are not allowed to cook for them. Almost all other "shabbos work" can be done for them by other people. The spirit of Shabbos is what can be at question, here -- however outright law would say that it's better to stay at the White House overnight than to drive home/be driven home.
Of course if a new unexpected, unplanned emergency suddenly came up, then they could drive/be driven, if needed. (That would apply to the Rabbi, as well.)
