RFK Jr.’s voice disorder is again popular on X.
From what I have noticed his sisters Courtney, Kerry, and Rory, and his brother Douglas, have similar voice problems. Some sound almost exactly like him, while others have a milder version. It is certainly genetic.
I don’t think other Kennedy cousins have it. Caroline and John don’t have this problem. Many people say it came from Rose Kennedy, but I don’t think she had the same kind of voice disorder.
I recently listened to the podcast Dead Certain: The Martha Moxley Murder. Stephen Skakel the brother of infamous Michael Skakel was speaking. His voice sounded identical to RFK Jr.’s. He surely has spasmodic dysphonia.
This condition is very rare. I think it’s unlikely that both the Kennedy family and the Skakel family had it by chance. I thibk it comes solely from the Skakel family, not the Kennedy family. Perhaps more Skakels sounds like this . So it is not a Kennedy disorder. Certainly not from flu shots or heroine. It is like they can’t accept their DNA has major flaws.
