In classical electromagnetism, the field at any given point in spacetime can be entirely determined by the presence and motion of all charged matter in the past light cone of that point. And for any point outside the event horizon, every point in its past light cone is also outside the horizon. So the field at that point is entirely determined by the past existence and motion of charged matter outside the horizon, what might exist inside the horizon is irrelevant to the field felt outside.
