Democratic primary candidate Robert F. Kennedy Jr. speaks to Sky News Australia host Piers Morgan about living with spasmodic dysphonia. “I had a very, very strong voice until I was 42 years old in 1996, I had an injury that caused a neurological disorder called spasmodic dysphonia,” he told Mr Morgan. “I cannot listen to my voice, when I go home I will not listen to this program, I can’t do it, I feel sorry for the people in your audience who have to listen to me. “But this is the best I’ve got right now.”
