Other forms: aides
An aide is an assistant to somebody important. A presidential aide, a senior aide, aides briefed the press.
It is the standard press word for a political staffer, and an unnamed aide is where most leaks come from. It comes from aide-de-camp, the officer attached to a general. Do not confuse it with aid, which is help itself rather than the person giving it.
