William John Kimmel

William John Kimmel, affectionately known as 'Billy,' is the son of comedian and late-night host Jimmy Kimmel and his wife Molly McNearney. Born in April 2017, Billy was diagnosed with a congenital heart condition shortly after birth, leading to multiple surgeries in his infancy. His health struggles have inspired his father to advocate for healthcare reform in the United States, making Billy a poignant symbol of the importance of access to medical care for children with preexisting conditions.
