John McCain, former presidential candidate and Republican Senator, has died at age 81 on August 25th, 2018. The politician suffered from glioblastoma, a type of cancerous brain tumor which is aggressive and thought to be incurable; McCain had announced just the day before he passed that he would stop treatment.

McCain was diagnosed with the disease in July 2017.

Before his diagnosis, Sen. John McCain was a well-known member of the U.S. Senate, having served for 30 years. He was also an American veteran, a naval bomber pilot, an avid world traveler, and a prison of war during Vietnam for five and a half years.

In McCain’s memoir, released this past May, the Senator writes:

“It’s been quite a ride. I’ve known great passions, seen amazing wonders, fought in a war, and helped make peace. I’ve lived very well and I’ve been deprived of all comforts. I’ve been as lonely as a person can be and I’ve enjoyed the company of heroes. I’ve suffered the deepest despair and experienced the highest exultation. I made a small place for myself in the story of America and the history of my times.”

Sen. McCain will be laid to rest in the Arizona Capitol on Wednesday, on what would have been his 82nd birthday. There will be a service for McCain in Arizona this week, where former presidents Barack Obama and George W. Bush have reportedly been asked to give eulogies.
