Except he doesn’t. In this story, he says his pills are working well, for which we are all glad. He definitely doesn’t say whether or not he stopped taking his medication before shooting the deceptive ads. A doctor says his movements seen on tape were caused by the medications, but is the doctor Fox’s physician? The story doesn’t say.
Fox has admitted in his own book going off medications before testifying to make his appearances before legislative committees more dramatic. It is not unreasonable to think he did the same thing before taping his many partisan ads. It would be very easy for Fox to put the whole thing to bed by simply calling a press conference to deny that he stopped taking his meds before taping. So far, he has not done so.
