But, how much was John worth at the time of his death?
Per theBBC, John was diagnosed with a brain tumor in July 2017.
After undergoing treatment for almost a year, John decided to end treatment in the summer of 2018.

In August that year, the McCain family made the sad announcement that the former presidential candidate had died.
With the senator when he passed were his wife Cindy and their family.
At his death, he had served the United States of America faithfully for 60 years."

I am so lucky to have lived the adventure of loving this incredible man for 38 years.
